Abstract
A polyaniline-graphitic carbon nitride-titanium dioxide composite catalyzes a radical cascade reaction of an aryl diazonium salt, DABCO·(SO2)2 and 3-bromoprop-1-ene to provide aryl allyl sulfones under visible light irradiation. A series of substrates were tolerated, providing the corresponding products in good yields. Moreover, the photocatalyst could be readily recovered and reused several times.
