For M+ = Na+, K+, the addition items M2[4] are created, which contain one new H-B and another new B-Bpin bond; for M+ = Li+, the H- ion is instantaneously transferred from the DBA-Me2 product to some other equivalent of HBpin to afford Li[5]. Although Li[5] might commonly be considered a [Bpin]- adduct of neutral DBA-Me2, it donates a [Bpin]+ cation to Li[SiPh3], producing the silyl borane Ph3Si-Bpin; Li2[DBA-Me2] with an aromatic main B2C4 band will act as the leaving te
