Abstract
Abstract: The photochemical a-cleavage reaction of bicyclooctanones 5-16 has been studied in benzene containing-3.5% methanol at 30 f 0.5" C. In all cases but one the only volatile products formed are the expected aldehyde and ketene (trapped as its methyl ester). The results collected in Table I indicate that conformational relaxation of the six-membered ring of biradical 2a competes successfully with disproportionation and that Scheme I must ...
