β-diketiminate titanium(III) complex with a phosphanylphosphido ligand, [MeNacNacTi(Cl)η2-P(SiMe3)-PtBu2}] (1) (MeNacNac− = [Ar]NC(Me)CHC(Me)N[Ar]; Ar = 2,6-iPr2Ph), was investigated towards selected chlorophosphanes, such as tBu2PCl, iPr2PCl, Cy2PCl, (Cy)tBuPCl, (Me)tBuPCl, (Ph)tBuPCl, Ph2PCl, (iPr2N)tBuPCl and (Et2N)2PCl. The reactions with tBu2PCl and Ph2PCl lead mainly to the earlier described complex [M
摘要β-二甲叉基钛(III)配合物与膦酰基磷配体[MeNacNacTi(Cl)η2-P(SiMe3)-PtBu2}](1)的反应性(MeNacNac- = [Ar] NC(Me)CHC( Me)N [Ar]; Ar = 2,6-iPr2Ph)已针对选定的氯膦进行了研究,例如tBu2PC1,iPr2PC1,Cy2PC1,(Cy)tBuPC1,(Me)tBuPC1,(Ph)tBuPC1,Ph2PC1,(iPr2N) tBuPC1和(Et2N)2PC1。与tBu2PC1和Ph2PC1的反应主要导致较早描述的复合物[MeNacNacTi(Cl)η2-P-PtBu2}](1a),而与iPr2PC1,Cy2PC1,(Cy)tBuPC1,(Me)tBuPC1和(Ph )tBuPCl导致不同的β-二甲叉基钛(IV)配合物与膦酰基次膦基配体的混合物:1a和[MeNacNacTi(Cl)η2-P-PiP
