Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The dimethyl aryloxide complexes [(PNP)M(CH₃)₂(OAr)] (M=Zr or Hf; PNP⁻=N[2‐P(CHMe₂)₂‐4‐methylphenyl]₂); Ar=2, 6‐<italic>i</italic>Pr₂C₆H₃), 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.</p> </abstract>
