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

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

Sahoo, Basudev; Surkus, Annette-Enrica; Pohl, Marga-Martina; Radnik, Joerg; Schneider, Matthias; Bachmann, Stephan; Scalone, Michelangelo; Junge, Kathrin; Beller, Matthias published an article in 2017, the title of the article was A Biomass-Derived Non-Noble Cobalt Catalyst for Selective Hydrodehalogenation of Alkyl and (Hetero)Aryl Halides.Recommanded Product: N,N-Diethylacetamide And the article contains the following content:

Hydrodehalogenation is a straightforward approach for detoxifications of harmful anthropogenic organohalide-based pollutants, as well as removal of halide protecting groups used in multistep syntheses. A novel sustainable catalytic material was prepared from biowaste (chitosan) in combination with an earth-abundant cobalt salt. The heterogeneous catalyst was fully characterized by transmission electron microscope, X-ray diffraction, and XPS measurements, and successfully applied to hydrodehalogenation of alkyl and (hetero)aryl halides with broad scope (>40 examples) and excellent chemoselectivity using mol. hydrogen as a reductant. The general usefulness of this method is demonstrated by successful detoxification of non-degradable pesticides and fire retardants. Moreover, the potential of the catalyst as a deprotection tool is demonstrated in a multistep synthesis of (±)-peronatin B (alkaloid). The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Recommanded Product: N,N-Diethylacetamide

On January 1, 2018, Satish, Sabbu; Srivastava, Ankita; Yadav, Pragya; Varshney, Salil; Choudhary, Rakhi; Balaramnavar, Vishal M.; Narender, Tadigoppula; Gaikwad, Anil Nilkanth published an article.Related Products of 456-12-2 The title of the article was Aegeline inspired synthesis of novel amino alcohol and thiazolidinedione hybrids with antiadipogenic activity in 3T3-L1 cells. 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

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
