A convenient, highly selective and metal-free synthesis of sulfoxides from alkenes and thiols using NHPI as an inexpensive and reusable organophotoredox catalyst is reported. The protocol involves radical thiol-ene/oxidation reaction cascade and utilizes visiblelight and air (O2) as inexpensive, readily available, non-toxic and eco-sustainable reagents to afford up to 96% yields of the product at
