Abstract
We describe an efficient photoredox system, relying on decatungstate/disulfide catalysts, for the hydrofunctionalization of styrenes. In this methodology the use of disulfide as co-catalyst was shown to be crucial for the reaction efficiency. This photoredox system was employed for the hydro-carbamoylation,-acylation,-alkylation and-silylation of styrenes, giving access to a large variety of useful building blocks and high-value molecules such as amides and unsymmetrical ketones from simple starting materials.
