Phosphane-Catalyzed Reactions of LAlH2 with Elemental Chalcogens; Preparation of [LAl(μ-E)2AlL] [E = S, Se, Te, L = HC{C(Me)N(Ar)}2, Ar = 2,6-iPr2C6H3]

Addition of catalytic amounts of a phosphane to a reaction mixture containing LAlH2 [2; L = HC{C(Me)N(Ar)}2, Ar = 2,6‐iPr2C6H3] and elemental Se or Te resulted in the formation of poorly soluble [LAl(μ‐Se)2AlL] (3) and [LAl(μ‐Te)2AlL] (4), respectively. The sulfur analogue [LAl(μ‐S)2AlL] (5) could n...

Description
Summary:Addition of catalytic amounts of a phosphane to a reaction mixture containing LAlH2 [2; L = HC{C(Me)N(Ar)}2, Ar = 2,6‐iPr2C6H3] and elemental Se or Te resulted in the formation of poorly soluble [LAl(μ‐Se)2AlL] (3) and [LAl(μ‐Te)2AlL] (4), respectively. The sulfur analogue [LAl(μ‐S)2AlL] (5) could not be obtained from the direct reaction of 2 with elemental sulfur; consequently, its synthesis was successfully achieved from the reaction of [LAlH2] and [LAl(SH)2]. A possible mechanism for the formation of [LAl(μ‐Se)2AlL] and [LAl(μ‐Te)2AlL] is discussed. The molecular structures of compounds 3−5 were determined by X‐ray structure analyses.
