摘要：

The formation of 3-ferrocenylmethyl-2,3-dihydrobenzofuran (5a) and similar products bearing cyclized substituents, when ferrocene or mixtures of ferrocene and ferrocenium ion are treated with o-allyloxybenzene- or o-but-3-enyloxybenzene-diazonium salts, provides unequivocal evidence for the intermediacy of free aryl radicals in the reaction of ferrocene with arenediazonium salts. The results are consistent with a mechanism involving electron transfer and dediazoniation followed by homolytic attack on ferrocenium ion.
