High yield synthesis of a neutral and carbonyl-rich terminal arylborylene complex

摘要

High yield synthesis of trans-[(Me_3P)(OC)_3Fe = BDur] (Dur, "Duryl" = 2,3,4,6-Me_4C_6H) is achieved by salt elimination and subsequent liberation of trimethylsilylbromide from K[Fe(CO)_3(PMe_3)SiMe_3l and Br_2BDur. Terminal borylene complexes contain double bonds between a transition metal and two-coordinated boron and are of fundamental interest, in addition to their close relationship to the isoelectronic carbonyls in terms of bonding and coordination modes.
