On irradiation in the presence of triplet sensitizers, vinylacetylene (1) may be added with its double bond to olefins , dienes , allenes , and diynes .The resulting multifunctionalized cyclobutane derivatives are characterized by spectroscopic and chemical methods.Since the ethinyl group of these codimers may be hydrated to the acetyl function, 1 represents a photochemical equivalent of methyl vinyl ketone which itself does not undergo the described photoadditions.When benzene (56) is employed as addition partner the primary product of the codimerisation, 54, isomerizes to vinylcyclooctatetraene (55).
