Addition of terminal or internal alkynes to a base‐free titanoceneoxide results in synthesis of the corresponding oxometallocyclobutene. With appropriate cyclopentadienyl substitution, these compounds undergo reversible CC reductive elimination offering a unique approach to cyclopentadienylmodification.
