【Abstract】 Photoinduced three component reactions between 1,2,4,5-tetracyanobenzene (TCNB), arylethene and water in aqueous acetonitrile solution are initiated by electron transfer between 1TCNB* and the alkene to give isocoumarin derivatives. Similar reactions with diols in place of water give the ipso substitution-nucleophilic trapping product without further intramolecular cyclization.更多还原
