Kumar, Ravinder; Mathur, Pavan published an article on February 5 ,2015. The article was titled 《Oxidation of phenyl propyne catalyzed by copper(II) complexes of a benzimidazolyl Schiff base ligand: Effect of acid/base, oxidant, surfactant and morphology》, and you may find the article in Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy.SDS of cas: 53332-79-9 The information in the text is summarized as follows:
Copper(II) complexes, Cu(L)X (X = Cl-, NO3-, NCS-) with a new N-substituted benzimidazole Schiff base ligand (HL) derived from 2-hydroxy-1-naphthaldehyde and N-methyl-2-(aminomethyl)benzimidazole, were used as catalyst for the oxidation of 1-phenylpropyne. The oxidation is carried out under mild conditions using stoichiometric amounts of oxidant and catalytic amounts of Cu(II) complex as catalyst. Effect of acid/base, oxidant, morphol. and surfactant was studied. Two major products of 1-phenylpropyne oxidation are the α-diketonic product, PhCOCOMe, and a terminal aldehyde, PhCCCHO. Diketone is the major product under acidic conditions while aldehyde formation is highest under basic conditions. The maximum conversion is found with the NO3- bound complex. GC-MS was used to find the percentage yields of products. SEM and PXRD of the reused complexes as catalyst suggest that morphol. affects the catalytic efficiency. In the experiment, the researchers used [(1-Methyl-1H-benzimidazol-2-yl)methyl]amine dihydrochloride(cas: 53332-79-9SDS of cas: 53332-79-9)
[(1-Methyl-1H-benzimidazol-2-yl)methyl]amine dihydrochloride(cas: 53332-79-9) belongs to imidazoles.Although other azole heterocycles are ubiquitous in a wide range of biologically active natural products, imidazole rings occur predominantly in the natural amino acid histidine. SDS of cas: 53332-79-9 In addition, imidazole rings are part of unnatural cyclic peptides and are used as ester isosteres in peptidomimetic studies.
