Reactivity study of a β-diketiminate titanium(III) complex with a phosphanylphosphido ligand towards chlorophosphanes. A new method of synthesis of β-diketiminate titanium(IV) complexes with versatile phosphanylphosphinidenes

Abstract

The reactivity of ab-diketiminate titanium(III) complex with a phosphanylphosphido ligand, [MeNacNacTi(Cl){g2-P(SiMe3)-PtBu2}] (1)(MeNacNac= [Ar]NC(Me)CHC(Me)N[Ar]; Ar = 2,6-iPr2Ph), was investigatedtowards selected chlorophosphanes, such astBu2PCl,iPr2PCl, Cy2PCl, (Cy)tBuPCl, (Me)tBuPCl, (Ph)tBuPCl, Ph2PCl, (iPr2N)tBuPCl and (Et2N)2PCl. The reactions withtBu2PCl and Ph2PCl lead mainly to theearlier described complex [MeNacNacTi(Cl){g2-P-PtBu2}] (1a), while the reactions withiPr2PCl, Cy2PCl,(Cy)tBuPCl, (Me)tBuPCl and (Ph)tBuPCl lead to mixtures of differentb-diketiminate titanium(IV) com-plexes with phosphanylphosphinidene ligands:1aand [MeNacNacTi(Cl){g2-P-PiPr2}] (1b),1aand[MeNacNacTi(Cl){g2-P-PCy2}] (1c),1aand [MeNacNacTi(Cl){g2-P-P(Cy)tBu}] (1d),1aand [MeNacNacTi(Cl){g2-P-P(Me)tBu}] (1e),1aand [MeNacNacTi(Cl){g2-P-P(Ph)tBu}] (1f) respectively. The newly obtainedcompounds1cand1dwere isolated and their identities unambiguously confirmed by X-ray diffraction,NMR spectroscopy and elemental analysis. In the reaction with (Et2N)2PCl the related titanium(IV) com-plex is not observed, but the phosphetanetBu2P-P(l2-PNEt2)2P-PtBu2(3) is formed
