Reaction of lithio 1-trimethylsilylcyclopropane or its formal equivalent [CH2 = C(Li)SiMe3; CH2I2, EtZnI] with carbonyl compounds leads to carbinols which dehydrate without rearrangement. Other attempts to induce ring expansion of the silicon substituted three-memberedring by ionic pathways are reported.

does add satisfactorily to carbonyl compounds and the subsequent Simmons-Smith cyclopropanation provides the desired cyclopropyl carbinols, shorter routes involving the 1-trimethylsilylcyclopropyl anion were sought. The sequence based upon reductive lithiation of 1-(trimethylsilyl)-1-phenyl-thiocyclopropane proved less than satisfactory. In contrast, metalation of 1-bromo-1-(trimethylsilyl)cyclopropane
