Mechanistic study of CuH-catalyzed hydroarylation of alkenes with polyfluoroarenes involving C–F bond functionalization: noncovalent interaction-controlled regioselectivity

Noncovalent interactions override electronic effects on the regioselectivity of the S N Ar step that cleaves a C–F bond of polyfluoroarenes in a CuH-catalyzed hydroarylation of alkenes.
