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 = iPr2NEt, but with L = Me3N, Me2NPr, or several N-heterocyclic carbenes, highly reactive dicationic dimers are formed.
从单价氢桥盐H(H2B-L)2 [B(C6F5)4]¯（L=路易斯碱）中脱去氢化物，会生成可观察到的伯硼翁阳离子，但 L 为 iPr2NEt 时，L 为 Me3N、Me2NPr 或几种 N-杂环卡宾时，会形成高活性的二阳离子二聚体。
