The reaction of ketones with the titanocene reagent prepared by the treatment of 1,1-bis(phenylthio)cyclobutane with the low valent titanium species Cp2Ti[P(OEt)3]2 produced the corresponding alkylidenecyclobutanes. These compounds were successfully transformed into 2,2-disubstituted cyclopentanones by the epoxidation and subsequent ringenlargement. The similar reactions of the carbene complexes with
