Divergent Trideuteromethylthiolation and Aminotrideuteromethylthiolation of Alkenes with N -Fluorobenzenesulfonimide and CD 3 SSO 3 Na.

A metal-free oxidative trideuteromethylthiolation of alkenes with CD 3 SSO 3 Na using NFSI as an oxidant has been developed. The aminotrideuteromethylthiolation of a three-component reaction could be easily achieved in the presence of a cobalt catalyst. The divergent trideuteromethylthiolation of alkenes, readily available trideuteromethylthiolation reagent, and versatile synthetic strategy allow for late-stage modification of drug molecules.
