Resumen:
O-Arylation reaction is obtained when N-(2-halophenyl) indolo carboxamides are irradiated in a basic medium. On the basis of photochemical and photophysical experiments, we propose that 2-indolylbenzoxazole is formed by intramolecular electron transfer followed by fast dehalogenation of the halophenyl radical anion pendant moiety, finally a radicalradical collapse renders the observed product.
