A Pd(OAc)2/P(OPh)3 combination catalyzed Tsuji–Trost-type allylic amination under aerobic conditions. Both aromatic and aliphatic secondary amines were transformed into the corresponding allylic amines with a tiny amount of the catalyst system (typically 0.02 mol % Pd), only when allylic phosphates were employed as electrophiles. Other typical electrophiles, such as allylic acetate and carbonate, were
Pd(OAc) 2 /P(OPh) 3组合在有氧条件下催化辻-特罗斯特型烯丙基胺化。仅当使用烯丙基磷酸盐作为亲电子试剂时,芳族和脂肪族仲胺都可通过少量催化剂体系(通常为 0.02 mol% Pd)转化为相应的烯丙基胺。其他典型的亲电子试剂,例如乙酸烯丙酯和碳酸酯,具有轻微的反应性。机械实验表明,原位形成的 Pd(0) 配合物 Pd[P(OPh) 3 ] 3是一种活性物质。
