[Ph2PC(X)NR]− (X = S, NR, O) and [Ph2P(Q)C(S)NR]− (Q = S, O) have been shown to react with rhodium(I)- and iridium(I)-phosphine compounds to give stable complexes M(PPh3)2[Ph2PC(X)NR] (A) and M(PPh3)2[Ph2P(Q)C(X)NR] (B) (M = Rh, Ir) in which the ligands are bidentate. P, S(P) and O(P) are always coordinated and the coordination preference of the other atoms is: S > NR > O.
一些已知和新的杂烯丙基衍生物[Ph 2 PC(X)NR] -(X = S,NR,O)和[Ph 2 P(Q)C(S)NR] -(Q = S,O)具有已显示与铑(I)-和铱(I)-膦化合物反应生成稳定的络合物M(PPh 3)2 [Ph 2 PC(X)NR](A)和M(PPh 3)2 [Ph 2 P(Q)C(X)NR](B)(M = Rh,Ir),其中配体是双齿的。P,S(P)和O(P)始终保持配位,其他原子的配位偏好为:S> NR>O。
