Unexpected transformations of an allyl group in a gallium complex with the redox-active dpp-bian ligand

The complex [(dpp-bian) − Ga(σ-allyl)Cl] ( 1 ), which was prepared by the oxidative addition of two equivalents of allyl chloride to digallane [(dpp-bian) 2− Ga—Ga(dpp-bian) 2− ], reacts with one equivalent of sodium in tetrahydrofuran (THF) at 40 °C to afford the complex [(dpp-bian) 2− (THF)Ga] 2 (...
