Treatment of β-diketiminato Mg and Ca amidoborane compounds with B(CF) induces hydride elimination and formation of alkaline earth hydrido-tris(pentafluorophenyl)borate derivatives. Both species react with CO to provide formate complexes, one of which has been structurally characterised, and may be applied to the highly selective reductive hydroboration of CO with pinacolborane (HBpin) to provide the methanol equivalent, CHOBpin.
