Rhenium-catalyzed C–H aminocarbonylation of azobenzenes with isocyanates

Abstract

The first C–H aminocarbonylation of azobenzenes with isocyanates is achieved by using rhenium-catalysis, which provides an expedient and atom-economical access to varied o-azobenzamides from readily available starting materials. The reaction efficiency can be enhanced by the catalytic use of sodium acetate via accelerated C–H bond activation.
