A combination of gold chloride organometallic complex and a silver salt was used to catalyze intermolecular hydroamination of activated alkenes, i.e aza-Michael reactions. The gold-catalyzed reactions of activated alkenes with nitrogen substrates were investigated and found to afford various mono- and dihydroamination products, the latter being rare and original. After flash chromatography, gold NHC
氯化金有机金属络合物和银盐的组合用于催化活化烯烃的分子间加氢胺化,即氮杂-迈克尔反应。研究了活化烯烃与氮底物的金催化反应,发现可以提供各种单氢胺化和二氢胺化产物,后者是罕见的和原始的。快速色谱后,金 NHC 催化剂可以作为氢氧化金 NHC 复合物回收。当与银盐结合时,金络合物再次导致活性加氢胺化催化剂。
