LiAlH4 to give the heterobimetallic complex 2 of the composition [(12-Al)Li]. Complex 2 was characterised by 1H-, 13C-, 27Al- and 7Li-NMR spectral data. Also, 2 when used in catalytic amounts accelerates Michaeladdition of malonates and thiophenol to α,β-unsaturated compounds like aldehydes, ketones, cyano and nitro compounds with high yield. Asymmetric induction in the Michael adducts has also been
