New Advances in Chemical Research in 2021. Reference of 76-84-6, In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. 76-84-6, Name is Triphenylmethanol, SMILES is OC(C1=CC=CC=C1)(C2=CC=CC=C2)C3=CC=CC=C3, belongs to isothiazole compound. In a article, author is Kalogirou, Andreas S., introduce new discover of the category.
Readily available 3-bromoisothiazole-5-carbonitriles bearing various C-4 substituents [H, CO2R C N and halogen (CI or Br)], react with either pyrrolidine or morpholine to give, in most cases, the 3-amino-substituted derivatives in high yields. The reaction of 3-bromoisothiazole-4,5-dicarbonitrile, however, varied with the nucleophilicity of the dialkylamine: pyrrolidine led to cleavage of the isothiazole ring to give 2-[di(pyrrolidin-1-yl)methylene]malononitrile while morpholine led to the expected 3-(morpholin-4-yl)isothiazole-4,5-dicarbonitrile. By comparison, 3-chloroisothiazole-4,5-dicarbonitrile reacted with pyrrolidine to give surprisingly, 3-chloro-5-(pyrrolidin-1-yl)isothiazole-4-carbonitrile as the major product, while with morpholine the major product was the expected 3-(morpholin-4-yl)isothiazole-4,5-dicarbonitrile. The mechanisms of the transformations are discussed, together with rationalization for the formation of side products. Furthermore, the hydrolytic decarboxylation of methyl and ethyl esters of 3-dialkylaminoisothiazoles using both conventional heating and microwave irradiation is reported. (C) 2014 Elsevier Ltd.
