✦ Synopsis

Arylpropiolyl chlorides undergo dimerization to a mixture of cis-and trans-alkylidenecyclobutane-1,3-diones. The structures of these products have been established by an X-ray study of the crystalline products formed by repeated crystallization or, alternatively, by thermal gradient sublimation.
