RADIOLYSIS OF ARALKYL KETONES
Products from the gamma irradiation of n-butyrophenone, isobutyrophenone, and benzoylcyclopropane were examined. Total yields of gaseous products decline markedly in the order named; G-values for total gas, at the lowest dose employed, namely, 6 x lO/sup 19/ ev/g, were 3.8, 0.62, and 0.13, respectively. Parallel studies of the decomposition of the ketones by ultra- violet light were performed. The predominant reaction in both radiolysis and photolysis of nbutyrophenone is a splitting to produce ethylene and acetophenone. This is presumed to be a molecular excr-tation process of the Norrish-Bamford type. Isobutyrophenone gives rise to a variety of gaseous products, in both radiolysis and photolysis, believed to anise chiefly from a splitting to benzoyl and C/sub 3/ radicals. Benzoyl cyclopropane is remarkably resistant to radiolytic decomposition; photolysis studies were not completed. (auth)
