Five aryl-substituted phenacetyl radicals (X = p-MeO, p-Me, H, p-Cl, p-CF 3 ) were generated by laser photolysis of the corresponding dibenzyl ketones in n-hexane and acetonitrile. The decarbonylation reaction was monitored through the rise in time-resolved absorption of the benzyl radical chromopho

Substituent effects in the reactivities of phenols towards polyacrylonitrile radicals have been studied in terms of Swain and Luptons' field (FR) and resonance (Rk) components of the substituent parameters and the unique positional weighting factors (fj and r j) proposed by Williams and Norrington,
The transient diary1 disulfide radical anions (RSSR-) were produced in nonaqueous solutions at room temperature by the flash photolysis of a solution of arylthiolate ion pair in the presence of the excess corresponding disulfide. The transient spectra were almost identical with those obtained from y
## Abstract The rate constants for the reaction of different cycloalkenylcarboxylic, cycloalkenylacetic acids, and phenylacetic acid with diazodiphenylmethane were determined in 12 aprotic solvents at 30Β°C. In order to explain the kinetic results through solvent effects, the secondβorder rate const
