Abstract

Abstract : Two neutral super electron donors (SEDs) based on C–C single bond have been developed. Abstract : This manuscript describes the preparation of [{(dpp-bian)BBr}Li(DME)3 ] (2, dpp-bian = 1, 2-bis[(2, 6-diisopropylphenyl) imino]acenaphthene) and [{(dpp-bian)BL} + Br − ] (5, L = DMAP; 6, L = 9-azajulolidine). The 4, 4-coupling of DMAP and 2, 2-coupling of 9-azajulolidine can be achieved either by the reaction of 2 with L, or by one-electron reduction of borenium cations 5 and 6 . Oxidation of 3 and 4 leads to C–C cleavage and regeneration of 5 and 6 . All new compounds have been structurally characterized.
