A cationic ruthenium(II) catalyst enabled highly efficient oxidative alkenylations of electron-rich arenes bearing removable, weakly coordinating carbamates, and allowed for cross-dehydrogenative CâH bond functionalization in an aerobic manner.

ortho-olefinated phenol carbamate, including a ruthenium(II)-catalyzed oxidative olefination of phenol carbamate with acrylates and a rhodium(III)-catalyzedalkynehydroarylation of phenol carbamate with internal alkynes through direct C–H activation, are reported. Both reactions afford substituted alkenes in a highly regio- and stereoselective manner.
