Li, Wei-Ze; Wang, Zhong-Xia published their research in Organic & Biomolecular Chemistry in 2021. The article was titled 《Nickel-catalyzed coupling of R2P(O)Me (R = aryl or alkoxy) with (hetero)arylmethyl alcohols》.Application of 141556-45-8 The article contains the following contents:
α-Alkylation of methyldiarylphosphine oxides with (hetero)arylmethyl alcs. was performed under nickel catalysis. Various arylmethyl and heteroarylmethyl alcs. can be used in this transformation. A series of methyldiarylphosphine oxides were alkylated with 30-90% yields. Functional groups on the aromatic rings of methyldiarylphosphine oxides or arylmethyl alcs. including OMe, NMe2, SMe, CF3, Cl, and F groups can be tolerated. The conditions are also suitable for the α-alkylation reaction of dialkyl methylphosphonates. After reading the article, we found that the author used 1,3-Dimesityl-1H-imidazol-3-ium chloride(cas: 141556-45-8Application of 141556-45-8)
1,3-Dimesityl-1H-imidazol-3-ium chloride(cas: 141556-45-8) is a ligand for arylation of aldehydes and for carbene catalyzed intermolecular arylation of C-H bonds. It is used as a phosphine-free ligand in various metal-catalyzed coupling reactions, often with advantageous results in difficult cases.Application of 141556-45-8
