title: Reaction of a dialumene-benzene adduct with diphenylacetylene: formation of 3,4-dialuminacyclobutene and 5,6-dialuminabicyclo[2.1.1]hex-2-ene derivatives.
abstract: Reaction of a dialumene-benzene adduct bearing bulky aryl substituents with diphenylacetylene was found to give a novel 5,6-dialuminabicyclo[2.1.1]hex-2-ene derivative in addition to the 3,4-dialuminacyclobutene derivative, the formal [2+2]cycloadduct of an intermediary dialumene with diphenylacetylene. The molecular structure of the newly obtained 5,6-dialuminabicyclo[2.1.1]hex-2-ene has been elucidated by X-ray crystallographic analysis.
