β-Stannyl carbonylcompounds, when treated with Lewis acids, afforded cyclopropane derivatives or ketones, and the reaction was applied to the synthesis of β,γ-enones from α, β-enones.

Reactions of β-trimethylstannylcyclohexanones with peracids: investigations into the stannyl-directed Baeyer–Villiger reaction

The trimethylstannyl substituent raises the migratory aptitude of a primary β-carbon to be above that of a not otherwise activated secondary or tertiary carbon. This is apparent from the exclusive formation of the alkene acids 9â11 from BaeyerâVilliger reaction of the β-stannyl cyclohexanones 3â5. The stereoelectronic requirements of the stannyl-directed BaeyerâVilliger reaction were investigated using the axial β-trimethylstannylcyclohexanone 20.

Silicon and tin substituents surprisingly have only a moderate directing effect on the TiffeneauâDemjanov reaction. The low selectivity is rationalised as being due to the reactive nature of the diazonium ion leaving group, the weaker oxydiazene leaving group was found to give better yields of the silicon-directed ring expanded product.
