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