R/X exchange reactions in cis-[M(R)2P(X)(NMeCH2)2}2] (M = Pd, Pt; R = aryl, alkyl; X = Cl, Br) were achieved for the first time to give cis-[M(X)2P(R)(NMeCH2)2}2]. DFT calculations suggested that the exchange reaction proceeds via a phosphenium intermediate.
对于顺式-[M(R)2 P(X)(NMeCH 2)2 } 2 ](M = Pd,Pt; R =芳基,烷基; X = Cl,Br),进行R / X交换反应。第一次给出顺式-[M(X)2 P(R)(NMeCH 2)2 } 2 ]。DFT计算表明交换反应通过via中间体进行。
