A New Type of Induced Decomposition. II. Decomposition of Phenylpropioloyl Peroxide and t-Butyl Phenyl-peroxypropiolate in Solution

Decomposition of phenylpropioloyl peroxide and t-butyl phenylperoxypropiolate in cumene, toluene, and cyclohexane was investigated. Product analysis and kinetic study together with the findings that radicals separately generated caused the decomposition of these peroxides demonstrate of a new type of induced decomposition involving radical attack on the triple bond of these peroxides and subsequent β-scission.
