title: Terminal stibinidene ligands. Generation of CpCp*Hf=Sb(dmp) and trapping reactions with PMe3 and 2-butyne.
abstract: Treating CpCp*HfMe(OTf) (1) with LiSbH(dmp) results in formation of CpCp*HfMe(SbHdmp), which undergoes alpha-abstraction to liberate methane and generate CpCp*Hf=Sb(dmp), which is thermally unstable but can be trapped with PMe(3) or 2-butyne to give CpCp*Hf(PMe(3))=Sb(dmp) (2) and CpCp*Hf[eta(2)-Sb,C:Sb(dmp)C(Me)=C(Me)] (3), respectively.
