Cationic Terminal Borylene Complexes: Structure/Bonding Analysis and [4+1] Cycloaddition Reactivity of a BN Vinylidene Analogue

Abstract

Charge changes everything: The cationic terminal aminoborylene complex [CpFe(CO)2(BNCy2)]+[BArF4]− (1, Cy= cyclohexyl, ArF=3,5-(CF3)2C6H3; Fe orange, B green, N blue, O red, C gray) was structurally characterized. DFT studies (see HOMO−2) indicate delocalized π bonding along the linear Fe-B-N framework and significant FeB and BN multiple-bond character.
