Manganese-catalyzed sequential C–H and C–C/C–Het bond activation to synthesize allylic alcohols, allylated arenes, functionalized cyclopentenes and skipped dienes is reported. This protocol can be readily scaled up and various coupling partners are applied in manganese catalysis for the first time. Moreover, manganese-catalyzed alkenyl C(sp2)–H activation is also shown. Complimentary to the standard

A rhodium(III)-catalyzed C–C coupling between 2-vinyloxiranes and arenes directed by different chelating groups has been realized via a C–Hactivation pathway. This reaction proceeded under conditions with a low catalyst loading, and allylic alcohols were isolated as the coupling products. A series of benzoazepanes has been synthesized by following this coupling.
