Bifunctionalization of styrene through ring-opening-recombination strategy of phenylpropathiazole salt

Abstract

By opening the ring of a benzothiazole salt, we provide a sulfur source for the bifunctional reaction of styrene. The ring-opening-recombination reaction of the benzothiazole salt simultaneously constructs new C–S, C–O, and CO bonds after C–S bond breaking. The reaction proceeds in green solvents, requires no transition metal catalyst, and is compatible with many functional groups.
