The dimethyl aryloxide complexes [(PNP)M(CH 3 ) 2 (OAr)] (M=Zr or Hf; PNP − =N[2‐P(CHMe 2 ) 2 ‐4‐methylphenyl] 2 ); Ar=2,6‐ i Pr 2 C 6 H 3 ), which were readily prepared from [(PNP)M(CH 3 ) 3 ] by alcoholysis with HOAr, undergo photolytically induced α‐hydrogen abstraction to cleanly produce complexes [(PNP)M=CH 2 (OAr)] with terminal methylidene ligands. These unique systems have been fully characterized, including the determination of a solid‐state structure in the case of M=Zr.
