Abstract

Two aluminum complexes [LAl(μ-S)₂AlL] (1) and [LAl(SeH)₂] (2) were synthesized in good yield by reacting one equivalent of LAlH₂ (L = HC(CMeNAr)₂, Ar = 2,6-Et₂C₆H₃) with one equivalent of S and with two equivalents of Se without any catalysts, respectively. Complexes 1 and 2 have been characterized by ¹H and ¹³C NMR, elemental analyses, and single crystal X-ray structural analysis. Furthermore, the good catalytic activity of 1 as bimetallic Lewis acid catalyst for the addition reaction of TMSCN to aldehydes and aldimine condensation reactions, respectively, were investigated.
