Formation of the monoanion [ArP(BH3)(mu-BH2)2H]- with a symmetrically bridging hydride from the attempted synthesis of the dianion [ArP(BH3)3]2

Addition of an excess of BunLi to the bis(borano)phosphide complex [Ar*PH(BH3)2]-Li+ 1 (Ar* = 2,4,6-tri-tert-butylphenyl) and subsequent treatment with BH3, gives the anionic complex [Ar*P(BH3)(mu-BH2)2H]-Li+ 2 instead of the expected tris(borano)phosphide dilithium, [Ar*P(BH3)3]2-2Li+ 3.
