Terminal stibinidene ligands. Generation of CpCp*HfSb(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 α-abstraction to liberate methane and generate CpCp*HfSb(dmp), which is thermally unstable but can be trapped with PMe3 or
