TiO2-supported gold nanoparticle catalyst was found to allow the N-formylation of various amines, including normally unreactive anilines, using CO2 as the carbonyl source under a H2 atmosphere. A series of reducible functional groups, such as olefins, halogens, carbonyls, carbamates and cyano moieties, were completely retained during the formylation, demonstrating the highly selective formylation of
发现使用TiO2负载的金纳米颗粒催化剂在H2气氛下使用CO2作为羰基源,可以使各种胺(包括通常未反应的苯胺)进行N-甲酰化。一系列可还原的官能团,例如烯烃,卤素,羰基,氨基甲酸酯和氰基部分,在甲酰化过程中被完全保留下来,表明了功能胺的高度选择性甲酰化。还发现该催化剂是可重复使用的,而没有任何活性或选择性的损失。
