| Abstract: | The dimethyl aryloxide complexes (PNP)M(CH3)2(OAr)] (M=Zr or Hf; PNP?=N2‐P(CHMe2)2‐4‐methylphenyl]2); Ar=2,6‐iPr2C6H3), which were readily prepared from (PNP)M(CH3)3] by alcoholysis with HOAr, undergo photolytically induced α‐hydrogen abstraction to cleanly produce complexes (PNP)M=CH2(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. |
