The determination, by means of isotope dilution analysis, of the molar ratio of p-methoxybiphenyl-14C, 4-methoxy-2′-nitrobiphenyl-14C, 4-methoxy-3′-nitrobiphenyl-14C, 4-methoxy-4′-nitrobiphenyl-14C, 2-chloro-4′-methoxybiphenyl-14C, 3-chloro-4′-methoxybiphenyl-14C and 4-chloro-4′-methoxybiphenyl-14C formed through the reaction of N-nitrosoacet-P-anisidide-(phenyl-14C) in an equimolar mixture of nitrobenzene, chlorobenzene and benzene, is described. From the results, the partial rate factors of the ortho, meta and para positions for the homolytic p-methoxyphenylation were found to be 6.45, 1.19 and 8.36 for nitrobenzene and 3.08, 1.82 and 1.74 for chlorobenzene, respectively, the reactivity of the one position of benzene being taken as unity.
