A palladium-catalyzed intramolecular oxidative aminonitroxylationof unactivated alkenes, in which AgNO 3 functioned as amild nitrate reagent in the presence of PhI(OAc) 2 , hasbeen developed. Mechanistic studies suggest that this selectiveaminonitroxylation reaction likely resulted from a new oxidant PhI(ONO 2 ) 2 generatedin situ from AgNO 3 and PhI(OAc) 2 .
已开发出钯催化的未活化烯烃的分子内氧化氨基硝酰化反应,其中 AgNO 3 在 PhI(OAc) 2 存在下充当温和的硝酸盐试剂。机理研究表明,这种选择性氨基硝基化反应可能是由 AgNO 3 和 PhI(OAc) 2 原位生成的新氧化剂 PhI(ONO 2 ) 2 引起的。
