POLARISATION NUCLEAIRE INDUITE CHIMIQUEMENT: ETUDE COMPARATIVE DE LA DECOMPOSITION THERMIQUE ET PHOTOCHIMIQUE DE PEROXYDES D'ACYLE BENZOYLE

Article abstract of DOI:10.1016/0040-4020(80)80165-7

A comparative CIDNP study of the thermal and photochemical decomposition of acyl benzoyl peroxides PhCO2O2CR (R=methyl and isobutyl) has provided an explanation of the effect of the mode of initiation on the course of the decomposition of this class of peroxides and on the product distribution.The observed variations result from an important decrease (from 1E-8 sec to less than 1E-10 sec) in the lifetime of the benzoyloxy radical on changing from thermal to photochemical initiation.
