Abstract

Abstract: Photolysis of diphenyldiazomethane in six matrices (toluene, methylcyclohexane, benzene, diethyl ether, 2-propanol, and cyclohexene) and their deuterated modifications at low temperature gave rise to the metastable triplet ESR spectrum of diphenylcarbene. Chemical and kinetic isotope effects established that the mechanism of the signal decay was hydrogen atom abstraction by the triplet ground state of diphenylcarbene from the matrix ...
