Thioamide-Directed CpCo(III)-Catalyzed C–H Allylation of Ferrocenes

Herein, the first Cp*Co­(III)-catalyzed C–H allylation of ferrocene thioamides with allyl carbonates has been developed. This reaction is compatible with a wide range of functional groups, providing various allylated ferrocene derivatives in up to 90% yields. In addition, the C–H allylation protocol is also compatible with the use of vinylcyclopropanes as allylating reagents by merging C–H and C–C activation into one catalytic system. Mechanistic studies revealed that the thiocarbonyl-directing group plays a vital role in C–H activation.
