Addition of terminal or internal alkynes to a base-free titanocene oxide results in synthesis of the corresponding oxometallocyclobutene. With appropriate cyclopentadienyl substitution, these compounds undergo reversible C-C reductive elimination offering a unique approach to cyclopentadienyl modification.
末端或内部炔烃与无碱金属的二茂钛氧化物加成，可合成相应的氧代金属环丁烯。对于具有适当环戊二烯基取代的化合物，它们可经历可逆的 C-C 还原消除，从而提供了一种独特的方法来修饰环戊二烯基。
