Given
the similarity of multiple sp3 C–H bonds
in electronic properties and bond dissociation energy (BDE), regioselective
sp3 C–H bond functionalization remains a paramount
challenge. Here, we report a C-centered radical-mediated approach
for site-specific sulfonylvinylation of the C(sp3)–H
bond via the hydrogen atom transfer (HAT) process. The reaction features
mild conditions, broad substrate scope, and high regioselectivity
and stereoselectivity, manifesting the nontrivial synthetic potential
