On March 8, 2022, Liu, Jingjing; Gnanou, Yves; Feng, Xiaoshuang published an article.Quality Control of 1,3-Diphenylurea The title of the article was Expanding the Scope of Boron-Based Ate Complexes by Manipulating Their Reactivity: The Case of Cyclic Esters and Their (Co)Polymers. And the article contained the following:

The value and merit of triethylborane (TEB)-based ate complexes for the synthesis of various oxygenated polymers have been recently illustrated through successful examples of homopolymerization of epoxides and of their copolymerization with CO2, CS2, COS, anhydrides, isocyanates, etc. To further expand the scope of TEB-based initiating systems to a broader family of oxygenated polymers, they were used in this study to anionically polymerize cyclic esters and to copolymerize the latter monomers with propylene oxide (PO). To promote a fast and controlled ring-opening polymerization (ROP) of cyclic esters, hydrogen-bonding donors such as amines and (thio)ureas were added to TEB-based ate complexes used as initiators. Only under these conditions could the ROP of ε-caprolactone (CL), δ-valerolactone (VL), and L-lactide (LLA) proceed under controlled conditions with hardly detectable intra- or intermol. transesterifications. The role of amines and (thio)ureas when used alone or together in association with these boron-based initiators is discussed in detail. The controlled character of the polymerization of CL, VL, and LLA is attested by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-ToF MS) and other characterization techniques. As examples of the far-reaching potential of these borane-based ate complexes, random P(PO-co-VL) copolymers were derived by statistical copolymerization of VL with PO and various well-defined block copolymers-PPO-b-PVL, PVL-b-PPO, PPO-b-PCL, PPO-b-PLLA, and PPO-b-PVL-b-PPO-were grown by sequential polymerization of the corresponding monomers. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Quality Control of 1,3-Diphenylurea

On June 14, 2011, Meyer, Jorg; Keul, Helmut; Moller, Martin published an article.COA of Formula: C11H9NO3 The title of the article was Poly(glycidyl amine) and Copolymers with Glycidol and Glycidyl Amine Repeating Units: Synthesis and Characterization. And the article contained the following:

The synthesis and characterization of poly(glycidol-co-glycidyl amine), poly(glycidol)-block-poly(glycidyl amine), and poly(glycidol) end-capped with a glycidyl amine unit is reported. Copolymerization of ethoxyethyl glycidyl ether with epichlorohydrin using tetraoctylammonium bromide/triisobutylaluminium as catalyst leads to statistical or block copolymers. Sequential addition of the monomers to the initiator leads to block copolymers while simultaneous copolymerization of the monomers results in statistical copolymers. The resulting polyethers with protected hydroxymethyl and chloromethyl side groups were converted in three steps to poly(epoxide)s with hydroxymethyl and aminomethyl side chains. These polymers have a high potential for the preparation of multifunctional polymers since amine and alc. groups can be addressed selectively by electrophiles. An intermediate in the synthesis of these functional poly(epoxide)s are polyethers with hydroxymethyl and azidomethyl side chains. The azide group of these copolymers was further functionalized via a click reaction with propargyl alc. proving the reactivity of the polymer bound azide group. Furthermore, preparation of poly(glycidol)s bearing a glycidyl amine end group is reported. The experimental process involved the reaction of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione(cas: 5455-98-1).COA of Formula: C11H9NO3

And the article contained the following:

Excess adiposity is a hallmark of obesity, which is caused due to an imbalance between energy intake and energy consumed. Obesity is often associated with several metabolic disorders like dyslipidemia, cardiovascular diseases and type 2 diabetes. Earlier, the authors’ group had reported natural product Aegeline (amino-alc.) isolated from the plant Aegle marmelos as an anti-diabetic and anti-dyslipidemic compound With this background, the authors synthesized a series of novel amino alc. and thiazolidinedione hybrid mols. and studied their antiadipogenic activity. As a result, the authors have identified a potent hybrid compound (Z)-3-benzyl-5-(4-(3-(3,4-dichlorobenzylamino)-2-hydroxypropoxy)benzylidene)thiazolidine-2,4-dione as an inhibitor of adipocyte differentiation. The compound (Z)-3-benzyl-5-(4-(3-(3,4-dichlorobenzylamino)-2-hydroxypropoxy)benzylidene)thiazolidine-2,4-dione inhibits lipid accumulation and adipogenesis in 3T3-L1 preadipocyte cell line. Exposure of compound (Z)-3-benzyl-5-(4-(3-(3,4-dichlorobenzylamino)-2-hydroxypropoxy)benzylidene)thiazolidine-2,4-dione blocks mitotic clonal expansion and arrests cells in S-phase of cell cycle. Detailed anal. showed that compound (Z)-3-benzyl-5-(4-(3-(3,4-dichlorobenzylamino)-2-hydroxypropoxy)benzylidene)thiazolidine-2,4-dione decreases expression of two major transcription factors that are involved in adipocyte differentiation, PPARγ, C/EBPα, and other adipogenesis associated genes like aP2 and FAS. Thus, compound (Z)-3-benzyl-5-(4-(3-(3,4-dichlorobenzylamino)-2-hydroxypropoxy)benzylidene)thiazolidine-2,4-dione shows potential ability to inhibit adipocyte differentiation which can be used therapeutically for the treatment of obesity and its associated metabolic disorders. The experimental process involved the reaction of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide(cas: 456-12-2).Related Products of 456-12-2

Madej, Dominik; Konopko, Adrian; Piotrowski, Piotr; Krogul-Sobczak, Agnieszka published an article in 2020, the title of the article was Pd nanoparticles and mixture of CO2/CO/O2 applied in the carbonylation of aniline.Related Products of 102-07-8 And the article contains the following content:

CO2 is a compound of high stability which proves useful in some organic syntheses as a solvent or component decreasing explosivity of gases. It is also a good carbonylating agent for aliphatic amines although not for aromatic ones, the latter being carbonylated with phosgene or, as in our previous works, with CO/O2 in the presence of Pd(II) complexes. In this work we have used the mixture of CO/O2 and CO2 for carbonylation of aniline to N,N’-diphenylurea. After optimization of the reaction conditions (56% of CO2 in CO2/CO mixture) we studied the activity of three kinds of pre-catalysts: (a) Pd(II) complexes, (b) Pdblack, and (c) palladium nanoparticles (PdNPs) in the presence of derivatives of pyridine (XnPy). The highest conversion of aniline (with selectivity towards N,N-diphenylurea ca. 90%) was observed for PdNPs. The results show that catalytic cycle involves Pd(0) stabilized by pyridine ligand as active species. Basing on this observation, we put the hypothesis that application of PdNPs instead of Pd(II) complex can efficiently reduce the reaction time. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Related Products of 102-07-8

On November 30, 2020, Zhang, Hui; Cui, Xiaojing; Wang, Hongliang; Wang, Yuqi; Zhao, Yuhua; Ma, Hui; Chai, Lin; Wang, Yingxiong; Hou, Xianglin; Deng, Tiansheng published an article.Reference of 1,3-Diphenylurea The title of the article was Degradation of polycarbonate-based polyurethane via selective cleavage of carbamate and urea bonds. And the article contained the following:

Deep eutectic solvents (DESs) have attracted broad attention due to their low cost and toxicity, easy preparation, good biol. compatibility and similar characteristics to those of ionic liquids In this study, a DES system composed of choline chloride and urea has been applied for the controllable degradation of polyurethane (PU). By the combination of Fourier transform IR spectroscopy (FT-IR), NMR spectroscopy (NMR) and matrix-assisted laser anal. ionization time-of-flight mass spectrometer (MALDI-TOF-MS), the selective cleavage of carbamate and urea bonds with little damage on carbonate bonds was achieved in the DES system by the regulation of reaction conditions, which favored the recovery of both valuable polycarbonate diol (PCDL) and 3,3′-Dimethyl-[1,1′-biphenyl]-4,4′-Diamine (o-toluidine). The degradation rate of PU and the yield of PCDL reached 100% and 57.4% resp. under mild conditions (1 atm, 170°C, 8 h). A possible degradation mechanism was proposed based on the exptl. results, in which the synergistic effect of choline chloride and urea activated largely the carbamate bond and thus led to a controlled degradation of PU. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Reference of 1,3-Diphenylurea
