A rhodium(III)-catalyzed C-H allylation of (hetero)arenes by using 2-methylidenetrimethylene carbonate as an efficient allylic source has been developed for the first time. Five different directing groups including oxime, N-nitroso, purine, pyridine, and pyrimidine were compatible, delivering various branched allylarenes bearing an allylic hydroxyl group in moderate to excellent yields.

Directing strategy has been extensively exploited to maintain activity and selectivity for the rapid access to functionalized molecules and pharmaceutical targets. However, ‘one-to-one’ activation model was usually achieved through traditional directing strategy. Herein, we achieved ‘one-to-two’ activation model by slight modification of simple and practical ketoxime and amide functionality. With judicious choice of directing groups, Csp3—H and Csp2—H bond alkynylation reaction, and more significantly, dehydrogenative Csp3—H alkynylation, were realized, enabling the regio-divergent late-stage modifications of pharmaceuticals.

A rhodium(III)-catalyzed intermolecular C-H amination of ketoxime and iodobenzene diacetate-enabled N-N bond formation in the synthesis of indazoles has been developed. A variety of functional groups were well tolerated, providing the corresponding produc
