report the selective, non‐directed and cross‐dehydrogenative coupling of allylicC(sp3)−Hbonds with C(sp2)−Hbonds of (hetero)arenes. The methodology employs olefins and (hetero)arenes which are abundantly available chemical feedstocks, and could be applied in late‐stage functionalization reactions of pharmaceuticals. Furthermore, the system exclusively delivers the allylic C−C coupling products highlighting

novel rhodium-catalyzed allylic substitution reaction using indium organometallics is reported. Aryl- and heteroarylindium reagents reacted in THF at 80 °C with primary and secondary allyl halides and their derivatives under rhodium(I) catalysis to afford the α-substituted products in good yields and with high regio- and stereoselectivity. The reaction takes place with substoichiometric amounts of
