transition-metal-free three-component trifluoromethyl heteroarylation of vinylethers under visible light irradiation. This protocol proceeded through a radical addition/cyclization sequence which hinged on the intrinsic nucleo/electrophilic reactivity of both the radicals, alkene, and alkynones, allowing β-trifluoromethyl alkyl thiochromones furnished with high efficiency and excellent functional group
