Treatment of 2 (M=Rh, Ir) with iminophosphoranophosphine ligands of the type Ph2PQP(Ph2)=NSiMe3 (Q=CH2, CH2CH2, 1,2-C6H4) afforded the new metallacycles through elimination of Me3SiCl, ultimately anchoring the ligand to the metal through a metal-nitrogen ? bond.The phosphine functionality completes the chelate.Cationic complexes of the type +PF6- (M=Rh or Ir; L2=Ph2PQPPh2NR where Q=CH2, CH(CH3), 1,2-C6H4, and R=p-C6F4CN, C6H2F(NO2)2, and C6H3(NO2)2 or L=Ph2PN=C(H)Ph) were readily prepared by treating 2 with L2 and KPF6.The detection and chemical shift determination of the insensitive 103Rh nucleus was easily accomplished via 31P detected indirect two-dimensional 31P, 103Rh NMR spectroscopy.The 103Rh, 1H, and 31P NMR data are discussed.Key words: rhodium, iridium, phosphoranimine, iminophosphine, Rh NMR.

A new heterodifunctional ligand system Me3EN=PPh2(CH2)nQPhw (E = Si, Ge; Q = P, As; n = 1, 2) has been developed.These heterodifunctional ligans provide hard (N) and solf (P, As) base character appropriate for combination with "early" and "late" transition metals respectively to form chelate and monodentate complexes.In addition M-N ? bond formation by means of metaathetical Me3EX elimination leads to a variety of useful functionalized phosphanes.Interactions with Ti(IV), Mo(0), W(0), Pd(II), Rh(I) and Ir(I) indicate the versatility of these ligands.
