Iron-mediated C-H coupling of arenes and unactivated terminal alkenes directed by sulfur

Cavanagh, Craig W.,Aukland, Miles H.,Hennessy, Alan,Procter, David J.

, p. 9272 - 9275 (2015)

A sulfur-directed Fe(iii)-mediated ortho C-H coupling of arenes with unactivated terminal alkenes gives products of regioselective alkene chloroarylation. The novel mechanism involves redox-activation of the arene partner and alkene addition to the result
