[R m] M species react with a-nitro olefins showing an unusual aptitude for a preferential transfer of saturated alkyl groups;[R2AlR'2] M (R'= phenyl, benzyl, allyl) species, on the other hand, are able to transfer unsaturated groups with high chemoselectivity. In particular, dialkyldiallylalanates react with a-nitro olefins to give either &nitro olefins or the corresponding y, &unsaturated ketones in very good yields. This reaction, synthetically ...
