Aminations can be efficiently run, under plug flow conditions on water, catalyzed by low levels of a recyclable palladium precatalyst. General protocols to couple amines, both aryl and aliphatic, with aryl/heteroaryl bromides have been developed. Further highlights include “on water” conditions, short reaction times, recycling of the reaction medium, low levels of residual Pd in the isolated products
在低含量的可回收钯预催化剂的催化下,胺化反应可以在水的活塞流条件下高效进行。已经开发出将芳基胺和脂肪族胺与芳基/杂芳基溴化物偶联的通用方案。进一步的亮点包括“水上”条件、短反应时间、反应介质的回收利用、分离产物中残留 Pd 含量低以及作为绿色指标的低 E 因子,所有这些特征都展示了这种胺化反应通常运行的替代方案在批处理模式下。
