Abstract

Thermal decompositions of N-benzhydryl-a, a-diphenylnitzone (1) and the para- tetradeuterated analogue 1-d4 in several solvents are reported. Mass spectral analyses of recovered nitrones and/or 0-benzhydryl ethers were performed. These data are combined with previously reported spectroscopic rate constants for the decomposition of 1 to evaluate the true carbon-nitrogen homolysis rate constant and the relative rate constants for (a) ...
