e-Acetoxy-8,y-unsaturated nitriles react at room temperature with malonates and acetoacetates in the presence of palladium-phosphine complexes as a catalyst to give y-substituted a,8-unsaturated nitriles selectively. Also yacetoxy-a,8-unsaturated ester was attacked at y-position by malonate.
Treatment of c~-silyl-cc,[~-unsaturated enones, readily preparable as regio-and stereodefined compounds in high yields, with either 2 equiv, oflCl or one equiv, each oflC1 and A1C13 provides the corresponding cc-iodo-a,[3unsaturated enones in high yields.
