The addition of Lewis bases to a cyclic (alkyl)(amino)carbene (CAAC)-supported dihydroboron triflate yields the mixed doubly base-stabilised dihydroboryl cations [(CAAC)BH<sub>2</sub>L]<sup>+</sup>. Of these, [(CAAC)<sub>2</sub>BH<sub>2</sub>]OTf (OTf = triflate) underwent facile two-electron reduction with KC<sub>8</sub> owing to a 1,2-hydride migration from boron to the carbene carbon to yield a stable hydroboryl anion. One-electron oxidation of the latter yielded the first neutral hydroboryl ...[more]
