Abstract
Benzenediazonium tetrafluoroborate together with one equivalent of pyridine provides a convenient source of phenyl radicals via the homolysis of N-phenylazopyridinium tetrafluoroborate. Partial rate factors and total rate ratios have been determined for attack of a number of aromatic substrates by phenyl radicals produced in this way and are found to be similar to the values obtained using benzoyl peroxide as the source of phenyl radicals. The ratios of isomers formed in the decompositions in moderate and in large excesses of pyridine differ from one another. The results are discussed.
