Synthesis of [LAl(µ-S)^sub 2^AlL] (L = HC(CMeNAr)^sub 2^, Ar = 2,6-Et^sub 2^C^sub 6^H^sub 3^) with the insertion of sulfur into the Al–H bonds of LAlH^sub 2^ and its application in catalysis

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...

Summary: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.
