Abstract

Treating CpCp*HfMe(OTf) (1) with LiSbH(dmp) results in formation of CpCp*HfMe(SbHdmp), which undergoes α-abstraction to liberate methane and generate CpCp*Hf [double bond, length as m-dash] Sb(dmp), which is thermally unstable but can be trapped with PMe₃ or 2-butyne to give CpCp*Hf(PMe₃)Sb(dmp) (2) and CpCp*Hf[η²-Sb,C:Sb(dmp)C(Me)C(Me)] (3), respectively.
