γ-Trialkylstannyl ketones underwent cyclobutanation, C-C bond cleavage, or 1,5-hydride shift, depending upon the substitution pattern of the substrates.

Treatment of γ-hydroxyalkyl stannanes with lead tetraacetate in refluxing benzene leads to the stereospecific formation of (E) and (Z)-keto olefins according to the stereochemistry of the starting materials in excellent yield.

Tertiary 1,5-hexadien-3-ols are transformed at room temperature into δ-ethylenic ketones in 35-90percent yields under two sets of conditions: treatment with one molar equivalent of mercuric trifluoroacetate followed by demercuration of the intermediate α-mercuro ketone with sodium borohydride; and treatment with 0.2 molar equivalent of the same salt in the presence of one molar equivalent of lithium trifluoroacetate or trifluoromethansulfonate.The reactions are highly stereoselective, the E isomer of the ketone forming 80-95percent of the product.The highest selectivity was observed under the second conditions.
