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

Abstract: Eine Ladung verändert alles: Der kationische terminale Aminoborylenkomplex [CpFe(CO)2(BNCy2)]+[BArF4]− (1, Cy=Cyclohexyl, ArF=3,5‐(CF3)2C6H3; Fe orange, B grün, N blau, O rot, C grau) wurde strukturanalytisch charakterisiert. DFT‐Studien zufolge (siehe HOMO−2) weist die Verbindung delokalisierte π‐Bindungen entlang des linearen Fe‐B‐N‐Gerüsts und signifikanten Fe‐B‐ und B‐N‐Mehrfachbindungscharakter auf.
