ArticleRh(III)-catalyzed direct C–H cyanation of N-methoxybenzamides using N-cyano-N-phenyl-p-Toluenesulfonamide (cas 1333-07-9)

Add time:08/19/2019    Source:sciencedirect.com

A new method has been developed for the mild and efficient Rh(III)-catalyzed direct C–H cyanation of a diverse range of N-methoxybenzamides using N-cyano-N-phenyl-p-toluenesulfonamide as an environmentally friendly and efficient cyanating reagent. This new reaction proceeded with good regioselectivity to provide direct access to a wide variety of valuable ortho-cyanated N-methoxybenzamides with board substrate/functional group tolerance.
