Abstract
The use of visible-light-absorbing transition metal photocatalysts enables an anti-Markovnikov hydrothiolation of olefins. Quenching of the photoexcited Ru*(bpz)32 catalyst with a variety of thiols generates key thiyl radical intermediates, that form adducts with a wide variety of olefins in excellent yield.
