di-Rh complexes based on 1,3-bis(3′-butylbenzimidazol-2′-ylidene)benzene were utilized as catalysts for hydrosilylation. Among the substrates investigated were aldehydes, ketones, α,β-unsaturated carbonyls, acyl chlorides, nitriles, alkenes, nitro groups, isocyanates, and tertiary amides. Additionally, carbon dioxide underwent hydrosilylation to produce dimethylphenylsilylformate. The catalysts compared
最近报道的两种基于1,3-双(3'-丁基苯并咪唑-2'-亚烷基)苯的空气和水稳定的di-Rh络合物被用作氢化硅烷化的催化剂。所研究的底物包括醛,酮,α,β-不饱和羰基,酰氯,腈,烯烃,硝基,异氰酸酯和叔酰胺。另外,使二氧化碳进行氢化硅烷化以产生二甲基苯基甲硅烷基甲酸酯。该催化剂与其他先前报道的氢化硅烷化催化剂相比具有很好的对比,并且在每种情况下,Rh–Cl催化剂都比Rh–I络合物更快,更具选择性。
