Rh-catalyzed oxidizing group-directed ortho C-H vinylation of arenes by vinylstannanes.

An efficient method for the synthesis of functionalized vinyl arenes from the reaction of N-methoxybenzamides or N-phenoxyacetamides with vinylstannanes via rhodium(iii)-catalyzed C-H activation is described. The application of the methodology for the synthesis of a natural product thalactamine and a 7-membered ring oxepine are also demonstrated.
