rings: Treatment of N‐arylallylamine with an aryl or alkenyl halide under palladium catalysis (see scheme; dba=dibenzylideneacetone, SPhos=2‐dicyclohexylphosphanyl‐2′,6′‐dimethoxybiphenyl) resulted in intramolecular cyclization to form the arylmethyl‐substituted aziridine with concomitant CC bond formation. The experiments for the elucidation of the reaction mechanism are also described.
疯狂的环:在钯催化下用芳基或烯基卤化物处理N-芳基烯丙胺(参见方案; dba =二亚苄基丙酮,SPhos = 2-二环己基膦基-2',6'-二甲氧基联苯)导致分子内环化形成芳基甲基取代的氮丙啶伴随有CC键的形成。还描述了阐明反应机理的实验。
