Rhodium(iii)-catalyzed cyanation of vinylic C–H bonds: N-cyano-N-phenyl-p-toluenesulfonamide as a cyanation reagent†
Abstract
Rh(III)-catalyzed direct vinylic C–H cyanation reaction has been developed as a practical method for the synthesis of alkenyl nitriles. N-Cyano-N-phenyl-p-methylbenzenesulfonamide (NCTS), a user-friendly cyanation reagent, was used in the transformation. Both acrylamides and ketoximes can be employed in the new C–H cyanation process.
