Abstract

The Far-UV (185 nm) solution-phase photochemistry of allenes has not been reported. Allene, which was studied under matrix isolation conditions at 8 K, photoisomerizes to cyclopropene and methylacetylene upon direct irradiation.'Contrasting behavior is provided by the vapor-phase direct photolysis of an earlier example, 1, 2-hexadiene, which yields ethylene, 1, 3-butadiene, and vinylcyclobutane, among other productsZa However, the ...
