Abstract
Photolysis of the title compounds results in efficient hydrogen transfer re action to produce 1,5-biradical intermediate, which does not form in the ph otolysis of a structurally similar compound. alpha-(o-tolyl)isobutyrophenon e. From their kinetic studies we have measured the rearrangement rate const ant of a substituted oxiranylcarbinyl radical. (C) 1999 Elsevier Science Lt d. All rights reserved.
