Mg-promoted reduction of a mixture of aromaticketones (or imines) and aliphatic carbonyl compounds in N,N-dimethylformamide (DMF) brought about unique mixed pinacol type of cross coupling to give unsymmetrical vicinal diols (or amino alcohols) or α-hydroxyketones in good to moderate yields. The reaction may be initiated by electron transfer from magnesium metal to an aromatic carbonyl compound possessing a

Abstract Imines can be readily allylated with samarium/allylbromide system to afford homoallylamines in satisfactory yields in THF under mild conditions.
