Abstract

CIDNP effects during the photolysis of 2, 2, 4, 4-tetramethylpentan-3-one (di-tert-butyl ketone) and 2, 4-dihydroxy-2, 4-dimethylpentan-3-one (di-POH ketone) in solutions containing the nitroxides TEMPO or SG1 [N-(2-methyl-2-propyl)-N-(1-diethylphosphono-2, 2- dimethylpropyl) aminoxyl] show that the tert-butyl radical reacts with these compounds by C– O-coupling, whereas the 2-hydroxy-2-propyl radical (POH) reacts by electron transfer ...
