Deprotonation of the terminal phosphido complex (PN)2La(PHMes) (1) results in the C–H-activation of one of the PN ligands, formally retaining the PHMes group. The reaction mechanism and the possible involvement of the transient phosphinidene complex 2 are investigated by theoretical and chemical means including a deuteration experiment employing (PN)2La(PDMes) (1-d). Furthermore, the thermal stability of product [K(2.2.2-cryptand)][(PN)(PNcyclo)La(PHMes)] (3b) is examined, giving the diphosphido complex [K(2.2.2-cryptand)][(PN)2La(P2Mes2)] (6).

瞬态镧次膦配合物

末端磷酸复合物(PN)2 La(PHMes)(1)的去质子化导致PN配体之一的C–H活化,正式保留了PHMes基团。通过理论和化学方法,包括使用(PN)2 La(PDMes)(1- d)的氘化实验,研究了瞬态次膦亚配合物2的反应机理和可能的参与。此外,检查了产物[K(2.2.2-cryptand)] [(PN)(PN)La(PHMes)](3b)的热稳定性,得到了二膦酸酯复合物[K(2.2.2-cryptand)]。 [(PN)2 La(P 2 Mes 2)](6)。
