On May 25, 2020, Kulal, Nagendra; John, Crowny; Shanbhag, Ganapati V. published an article.Recommanded Product: 1,3-Diphenylurea The title of the article was Rational design of bifunctional catalyst from KF and ZnO combination on alumina for cyclic urea synthesis from CO2 and diamine. And the article contained the following:

This study is mainly focused on the design of stable, active and selective catalyst for direct synthesis of 2-imidazolidinone (cyclic urea) from ethylenediamine and CO2. Based on the rationale for the catalyst properties needed for this reaction, KF, ZnO and Al2O3 combination was selected to design the catalyst. ZnO/KF/Al2O3 catalyst was prepared by stepwise wet-impregnation followed by the removal of physisorbed KF from the surface. High product yield could be achieved by tuning acid-base sites by varying the composition and calcination temperature The catalysts were characterized by various techniques like XRD, N2-sorption, NH3-TPD, CO2-TPD, TEM, XPS and FT-IR measurements. It is shown that acidic and basic properties of the solvent can influence the activity and product selectivity for this reaction. Under optimized condition; 180°C, 10 bar and 10 weight% catalyst in batch mode, 96.3% conversion and 89.6% selectivity towards the 2-imidazolidinone were achieved. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Recommanded Product: 1,3-Diphenylurea

Ielo, Laura; Miele, Margherita; Pillari, Veronica; Senatore, Raffaele; Mirabile, Salvatore; Gitto, Rosaria; Holzer, Wolfgang; Alcantara, Andres R.; Pace, Vittorio published an article in 2021, the title of the article was Taking advantage of lithium monohalocarbenoid intrinsic α-elimination in 2-MeTHF: controlled epoxide ring-opening en route to halohydrins.Name: 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione And the article contains the following content:

A straightforward preparation of different β-halohydrins RCR1(OH)CH2X [R = Ph, 4-ClC6H4, 1,3-dioxoisoindolin-2-yl, etc.; R1 = H, Me, CF3, Ph; X = Cl, Br, I] through boosted Kirmse’s elimination of the corresponding lithium monohalocarbenoids starting from epoxide. Crucial for the development of the method was the use of the eco-friendly solvent 2-MeTHF, which forces the degradation of the incipient monohalolithium, due to the very limited stabilizing effect of this solvent on the chem. integrity of the carbenoid. The uniformly high-yield, the full preservation of the embodied stereochem. information and the high regiocontrol – deduced by selectively preparing variously decorated motifs further document the potential of this operationally simpleand intuitive methodol. The experimental process involved the reaction of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione(cas: 5455-98-1).Name: 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione

On July 25, 2021, Dahnum, Deliana; Dang, Huyen Tran; Tran, Ngoc Tuan; Ha, Jeong-Myeong; Lee, Hyunjoo published an article.Electric Literature of 102-07-8 The title of the article was One-pot synthesis of 3D-ZIF-7 supported on 2D-Zn-Benzimidazole-Acetate and its catalytic activity in the methoxycarbonylation of aniline with dimethyl carbonate. And the article contained the following:

For the first time, three-dimensional Zeolitic Imidazole Framework (3D) ZIF-7 (Zn(BeIM)2, BeIM = benzimidazole) supported on two-dimensional (2D) Zn(BeIM)OAc (Zinc-Benzimidazole-Acetate) was synthesized by reacting Zn(OAc)2 and benzimidazole in a one-pot reaction. By modulating the amount of diethylamine during the reaction, the ZIF-7/Zn(BeIM)OAc with a 1 to 1 molar ratio was obtained when the reactant molar ratio of Zn(OAc)2 and benzimidazole was 1 to 1.5. It was found that 3D-ZIF-7 was synthesized first and then transformed into 2D-Zn(BeIM)OAc by the reaction with remaining Zn(OAc)2. The synthesized ZIF-7 (Zn(BeIM)2) supported on Zn(BeIM)OAc (1/1) showed enhanced catalytic performance in the methoxycarbonylation of aniline with di-Me carbonate. The yield of Me N-Ph carbamate reached 92.0% in 2 h at 190°C, which was higher than yields obtained using the single component catalysts ZIF-7 (69.9%) and Zn(BeIM)OAc (35.4%). Furthermore, this catalyst was successfully reused four times, maintaining an MPC yield of 92.0%-95.8%. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Electric Literature of 102-07-8

On June 30, 2020, Serrao, Reena Saritha; Shamshuddin, S. Z. Mohamed; Kumar, T. E. Mohan; Mandara, H. M. published an article.HPLC of Formula: 102-07-8 The title of the article was Catalytic microwave synthesis of biphenyl urea over mesoporous ZrO2-Al2O3. And the article contained the following:

Solid acids such as ZrO2, Al2O3 and ZrO2-Al2O3 were prepared and analyzed for their physico-chem. properties like surface acidity and acid site distribution by NH3-TPD, crystalline nature by powder XRD, functionality by FT-IR, morphol. by TEM and elemental anal. by ICP-OES methods. These solid acids were used as catalysts in the solvent-free synthesis of biphenyl urea using microwave irradiation technique starting from aniline and di-Me carbonate. Surface acidity and the phase of the solid acid were found to have a significant role in the synthesis of biphenyl urea. Up to (98%) yield of biphenyl urea with 100% selectivity was obtained in just 12 min. The activity of ZrO2-Al2O3 was compared with Mo(VI)/ZrO2 which is a solid super acid. For comparison, the reactions were also carried out by using conventional heating method. Kinetic studies were carried out to determine energy of activation of the solid acids. These solid acid catalysts were found to be reactivable and reusable when used for up to six reaction cycles. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).HPLC of Formula: 102-07-8

Fiorio, Jhonatan L.; Rossi, Liane M. published an article in 2021, the title of the article was Clean protocol for deoxygenation of epoxides to alkenes via catalytic hydrogenation using gold.Electric Literature of 5455-98-1 And the article contains the following content:

The epoxidation of olefin as a strategy to protect carbon-carbon double bonds is a well-known procedure in organic synthesis, however the reverse reaction, deprotection/deoxygenation of epoxides is much less developed, despite its potential utility for the synthesis of substituted olefins. Here, we disclose a clean protocol for the selective deprotection of epoxides, by combining com. available organophosphorus ligands and gold nanoparticles (Au NP). Besides being successfully applied in the deoxygenation of epoxides, the discovered catalytic system also enables the selective reduction N-oxides and sulfoxides using mol. hydrogen as reductant. The Au NP catalyst combined with triethylphosphite P(OEt)3 is remarkably more reactive than solely Au NPs. The method is not only a complementary Au-catalyzed reductive reaction under mild conditions, but also an effective procedure for selective reductions of a wide range of valuable mols. that would be either synthetically inconvenient or even difficult to access by alternative synthetic protocols or by using classical transition metal catalysts. The experimental process involved the reaction of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione(cas: 5455-98-1).Electric Literature of 5455-98-1
