Reductions of benzenediazonium ion to benzene, of m-chlorobenzenediazonium ion to chlorobenzene, and of several other diazonium ions have been studied in methyl and t-butyl alcohols at various alkoxide concentrations, under various atmospheres, and in the presence of various cosolvents. A mechanism (or mechanisms) involving aryl-radical intermediates is indicated by (a) the adverse effect of oxygen gas on dediazoniation yields ...
