on the structure of the acyl azides, consecutive hydrolysis toward corresponding primary amides was observed. ‘Direct’ aminocarbonylation of the same iodoalkenes was also carried out by using ammonium carbamate as ammonia source under mild conditions. The α,β-unsaturated primary amides, formed in a chemoselective reaction, were isolated in good to excellent yields.
碘代烯烃可通过其腙从酮中获得,经过钯催化的叠氮羰基化。根据酰基叠氮化物的结构,观察到连续水解为相应的伯酰胺。在温和条件下,使用氨基甲酸铵作为氨源也可以进行相同碘代烯烃的“直接”氨基羰基化。在化学选择性反应中形成的 α,β-不饱和伯酰胺以良好至极好的产率分离。
