Yingcharoen, Prapussorn; Natongchai, Wuttichai; Poater, Albert; D’ Elia, Valerio published an article in 2020, the title of the article was Intertwined chemistry of hydroxyl hydrogen-bond donors, epoxides and isocyanates in the organocatalytic synthesis of oxazolidinones versus isocyanurates: rational catalytic investigation and mechanistic understanding.Synthetic Route of 102-07-8 And the article contains the following content:

The use of hydroxyl hydrogen bond donors (HBDs) was investigated in cycloaddition of isocyanates to epoxides to afford 3-aryl-2-oxazolidinones I [R1 = H, 2-Me, 4-NO2, etc.; R2 = Et, CH2OCH2CH=CH2, CH2OCH2Ph, etc.] as a class of heterocycles with promising applications in pharmaceutical chem. In this work, a systematic investigation of readily available HBDs as catalytic components of binary systems for latter cycloaddition reaction was carried out. Such a study showed crucial role of HBDs’ pKa1 value in driving selectivity of reaction toward oxazolidinones as opposed to formation of oligomeric isocyanurates or ureas, with most acidic HBDs (pKa1: 3-4) displaying best catalytic performance. Mechanistic investigation with the support of DFT calculations allowed deeper insight into reaction dynamics and origin of exptl. observed chemoselectivity for cyclization vs. cyclo-oligomerization at different reaction temperatures, shedding light on a strictly intertwined chem. between the HBDs, isocyanates and epoxides. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Synthetic Route of 102-07-8

On January 31, 2018, Fadavi, Abdulhamid; Zarei, Maaroof published an article.Related Products of 27115-50-0 The title of the article was One-pot Vilsmeier reagent-mediated multicomponent reaction: A direct synthesis of oxazolones and Erlenmeyer azlactones from carboxylic acids. And the article contained the following:

N-Acylation of glycine with carboxylic acids RC(O)OH [R = C6H5, 4-pyridyl, 2-naphthyl, CH3CH=CH, etc.] was carried out by using the Vilsmeier reagent. The resulting N-acyl-α-amino acids RC(O)NHCH2C(O)OH were subsequently cyclodehydrated into oxazol-5-ones I via the Vilsmeier reagent. Finally, treatment of oxazol-5-ones I with aldehydes R1CHO [R1 = CH3, C6H5, 2-furyl, etc.] in the presence of the Vilsmeier reagent delivered Erlenmeyer azlactones II. By combining these steps, using the Vilsmeier reagent allowed direct one-pot conversion of carboxylic acids RC(O)OH into oxazol-5-ones I and direct one-pot conversion of carboxylic acids RC(O)OH into Erlenmeyer azlactones in the presence of aldehydes R1CHO. These Vilsmeier reagent-mediated multicomponent reactions proceeded smoothly in reasonable chem. yields at room temperature The chem. structure of the title compounds I and II was confirmed by spectral data. The experimental process involved the reaction of 2-(4-Methylbenzamido)acetic acid(cas: 27115-50-0).Related Products of 27115-50-0

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

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

And the article contained the following:

Ethanol-assisted liquefaction followed by a hydrotreating process was applied to the microalgal biomass of Chlamydomonas. The intent of the research was to develop process technol. to convert microalgae into drop-in fuels. The operation conditions of the ethanol-assisted liquefaction were optimized using the following variables: reaction temperatures (200-290°), ethanol concentration (10-90 volume%), residence time (0.5-2 h), and the catalyst (SO42-/ZrO2). The application of a higher ethanol concentration and the solid acid enhanced extraction of algal lipids and transesterification. The highest liquid yield of 93.7% for catalytic liquefaction was obtained under the reaction conditions of (290°, 90 volume% ethanol, and 0.5 h). Hydrotreating of the liquid products generated via liquefying microalgae was conducted over a Mo2C/Biochar catalyst at 340° and 3.44 MPa hydrogen. The obtained products contained predominantly hydrocarbon mols. falling into the diesel range.
