摘要：

Treatment of the phosphonium salt [PhP(CH2Ph)(3)]Cl with three molar equivalents of (BuLi)-Bu-n gives the dilithiated species [Li2PhP(CHPh)(3)]. The crystal structure of the monolithiated species as its TMEDA adduct has been determined. Treatment of the dilithiate species with [((eta -C5Me5)MX2](2) (M = Cr, X = Br; M = Rh, X = Cl) provides [(eta -C5Me5)M{eta (2)-PhP(CH2Ph)(CHPh)(2)}X] containing chelating phosphoniodiylide ligands which are thought to be the hydrolysis products of the target complexes [{PhP(CHPh)(3)M(C5Me5)].
