摘要

Two chalcogenide bridged bi-aluminum compounds [LAl(NMe₃)(μ-S)Al(NMe₃)L] (1) and [LAl(NMe₃)(μ-Se)Al(NMe₃)L] (2) were synthesized by reacting LAlH(NMe₃) (L = 4-methylbenzylidene-o-aminothiophenol) with one equivalent of sulfur and selenium without any catalysts in ambient temperature. Compounds 1 and 2 have been characterized by ¹H and ¹³C NMR, elemental analyses, and single crystal X-ray structural analysis. Furthermore, bi-aluminum compounds 1 or 2 were investigated as Lewis acid catalyst for the cyanosilylation of aldehydes and the condensation of aldimine and hydroboration of aldol ketones, respectively.
