Abstract
Effect of a 4-substituent in the pyridine ring upon the decomposition kinetics of benzoyl peroxide in 4-X pyridine/benzene binary mixtures (X= CH3, H, CN) has been studied. The second-order rate constant for the pyridine-induced decomposition was 2xl0-6l mol-1 s-1 and in 4-methylpyridine it was l0-5 l mol-1 s-1, a five-fold increase, whereas there was no nucleophilic attack on the peroxide oxygen atoms of benzoyl peroxide by 4-cyanopyridine. ...
