Abstract

Twofold distal C-H functionalization was accomplished by difunctionalization of nonactivated alkenes to provide rapid access to multifunctionalized molecules. We, hence, report the multicomponent ruthenium-catalyzed remote 1,n-difunctionalization (n = 6,7) of nonactivated alkenes with fluoroalkyl halides and heteroarenes in a modular manner. The meta-C(sp2)-H/C-6(sp3)-H distal functionalization featured mild conditions, unique selectivity, and broad substrate scope with a domino process for twofold remote C(sp2)-H/C(sp3)-H activation of the sequential formation of three different carbon-centered radicals. A plausible mechanism was proposed based on detailed experimental and computational studies.
