摘要

Three equivalents of LGa {L = HC[C(Me)N(2,6-i-Pr2C6H3)](2)} react with AsX3 (X = Cl, Br) by insertion into two As-X bonds, followed by the elimination of LGaX2 and formation of LGaAsGa(Cl)L (1) and LGaAsGa(Br)L (2). According to single crystal X-ray analysis, 1 and 2 each exhibit one Ga-As single bond and one Ga-As double bond. The pi-bonding contribution (9.71 kcal mol(-1) 1 and 9.44 kcal mol(-1) 2) was proved by variable temperature (VT) H-1 NMR spectroscopy, while the electronic structure of 1' was studied by quantum chemical calculations.
