(P,C)-Cyclometalated complexes deriving from naphthyl phosphines: versatile and powerful tools in organometallic chemistry

Résumé

The chemistry of (P,C)-cyclometalated complexes deriving from naphthyl phosphines [ Np (P,C)M] is presented and analysed in this review. The three main synthetic approaches, namely P-chelation assisted C-H activation, oxidative addition and transmetalation, are described and compared. If the naphthyl framework inherently predisposes the phosphorus atom and transition metal to interact, the rigid metallacycle may induce some strain and distortion, as apparent from the survey of the single-crystal X-ray diffraction structures deposited in the Cambridge Structural Database (77 entries with metals from group 7 to 11). Generally, the Np (P,C)-cyclometalation imparts high thermal and chemical robustness to the complexes, and a variety of stoichiometric reactions have been reported. In most cases, the metalacyclic structure is retained, but protodecyclometalation and ring-expansion have been sparingly observed. [ Np (P,C)M] complexes have also proved to be competent and actually competitive catalysts in several transformations, and they act as key intermediates in some others. In addition, interesting phosphorescence properties have been occasionally pointed out.
