摘要：

Preparation of titanacyclobutenes bearing vinyl substituents on the alpha-position of the metallacyclobutene ring is reported. Ring opening of such titanacyclobutenes is anticipated to afford divinylcarbene complexes (or their biradical analogs); reclosure of the titanacyclobutene ring then can result in either regeneration of the starting complex or in the formation of an isomeric titanacyclobutene. Experimentally, the instantaneous isomerization observed is consistent with rapid, reversible ring opening.
