very simple conjugate addition of aromatic and aliphatic amines to α,β-unsaturated carbonyl compounds under solvent-free conditions in the presence of catalytic amount of silicon tetrachloride is reported. The reaction of aryl and alkyl amines with different Michael acceptors gave the corresponding Michael adducts with simple catalyst and good to excellent yields.
报道了在无溶剂条件下,在催化量的四氯化硅存在下,芳香族和脂肪族胺与 α,β-不饱和羰基化合物的有效且非常简单的共轭加成。芳基和烷基胺与不同的迈克尔受体反应得到相应的迈克尔加合物,催化剂简单,产率好到极好。
