A visible-light-induced three-component sulfonyl-heteroarylation of vinyl ethers with sulfinates and five-membered heteroaryl chlorides is reported. This protocol proceeds via a photoinduced electron transfer process of electron-donor-acceptor complex between sulfinates and heteroaryl chlorides, enabling facile excess to β-sulfonyl and β-fluoromethyl α-oxy alkyl heteroaromatics under mild and catalyst-free
