Zirconium complexes supported by multidentate aminophenolato ligands were synthesized and characterized. The catalytic activities of neutral zirconium complexes and their cationic derivatives in the hydrophosphination of alkenes as well as heterocumulenes have been investigated and compared. Neutralcomplex 1 bearing a multidentate amino mono(phenolato) ligand exhibited high activity in hydrophosphination

(N3N = N(CH2CH2NSiMe3)33−; R = alkyl, aryl; R′ = R, H), have been shown to catalyze the hydrophosphination of terminalalkynes as well as that of symmetric aryl and alkyl carbodiimides. A mechanism based on insertion of the substrate into the Zr−P bond is proposed on the basis of competition experiments and model examples of stoichiometricinsertionreactions of polar, small-molecule substrates possessing
