Redox-neutral rhodium(iii)-catalyzed divergent synthesis of tetrasubstituted 1,3-enynes and alkynylated benzofurans

Herein, we report the rhodium-catalyzed tunable divergent synthesis of tetrasubstituted 1,3-enynes and alkynylated benzofurans via C−H alkenylation/DG migration and [3 + 2] annulation, respectively.
