The synthesis of cyclopropyl silylketones possessing a hydrocarbon group at 1-position of three-membered ring was investigated. The reaction of sulfoxonium ylide with α,β-unsaturated acylsilanes derivedfrom α,β-unsaturated aldehydes did not afford the desired acylsilane derivatives. Instead, the corresponding silylenolethers were yielded exclusively. On the other hand, the Corey-Chaykovsky cyclopropanation
