B(C6F5)3-catalyzed reductive denitrogenation of aromatic nitriles is reported, achieving the metal-free transformation of a cyano into a methyl group in a single synthetic operation. Tris(phenylsilyl)amine is liberated as the nitrogen-containing byproduct. On the basis of control experiments as well as a nuclearmagneticresonancespectroscopicanalysis, an SN1-type mechanism involving a trisilylammonium
报道了AB(C 6 F 5 ) 3催化芳族腈的还原脱氮,在单一合成操作中实现了氰基到甲基的无金属转化。三(苯基甲硅烷基)胺作为含氮副产物释放。在对照实验和核磁共振光谱分析的基础上,提出了以三甲硅烷基铵离子为关键中间体的S N 1 型机理。
