A Rh(III)-catalyzed C?H activation of azobenzenes in the coupling with diazo compounds has been realized, providing a straightforward strategy to access functionalized cinnolinium triflates in high yields. This protocol features silver free mild reaction conditions and compatibility with diverse functional groups. The coupling proceeds via initial Rh(III)-catalyzed C?H alkylation, followed by zinc triflate-mediated cyclization, where zinc triflate acts as a Lewis acid as well as a triflate source.

Irradiation (>/=300 nm) of methyl 2-phenyl-3,1-benzoxazepine-5-carboxylate in an alcohol afforded the Z-isomer of methyl 3-alkoxy-2-(2-benzamidophenyl)-acrylate as the major product.In contrast, thermal reaction of the oxazepine with a primary alcohol in
