Weakly Stabilized Primary Borenium Cations and Their Dicationic Dimers
Hydride abstraction from monocationic hydride bridged salts [H(H2B-L)(2)](+) [B(C6F5)(4)](-) (L = Lewis base) generates an observable primary borenium cation for L = iPr(2)NEt, but with L = Me3N, Me2NPr, or several N-heterocyclic carbenes, highly reactive dicationic chillers are formed.
