R. Schleyer, Gregory H. RobinsonThe reaction of N-heterocyclic carbene, L:, with BeCl2 quantitatively yields L:BeCl2 1 (L:
= :C{N(2,6-Pri2C6H3)CH}2). The
carbene-stabilized beryllium borohydride monomer L:Be(BH4)2 2 is prepared by the reaction of 1 with LiBH4. Compound 3, prepared
by the reaction of 2 with Na2[Fe(CO)4]·dioxane, represents an unusual “dual reduction”
of the imidazole ring (i.e., hydroboration of the CC backbone
and hydrogenation of the C2 carbene center).
