The photolysis of carbon suboxide in the presence of fluoroethylenes and alkanes
Abstract
Fluorinated alkynes are produced by the photolysis of carbon suboxide with light of wavelength shorter than 2800 Å in the presence of vinyl fluoride and 1,1-difluoroethylene. The reactivity of the singlet :CCO is with the ethylenes 0·144 and 0·097, respectively, of its reactivity with C3O2. The products of the photolysis of suboxide in the presence of methane, ethane, propane, and neopentane are ethylene, propene, isobutene, and 3,3-dimethylbut-1-ene. Isobutane yields isobutene, isopentane, and 3-methylbut-1-ene. The relative rates of formation of these products have been measured but no generally satisfactory mechanism for their formation can be suggested.
