Amidation of N-containing heteroaryl ferrocenes with 1,4,2-dioxazol-5-ones as the amidated reagents was achieved via a Rh-catalyzed direct C-H functionalization reaction. Under mild reaction conditions, a wide range of N-ferrocenyl amides were obtained-in up to 99% yield. Transformations of the amide group were also feasible.

The first catalytic and enantioselective CHalkylation of ferrocene derivatives with various alkenes was achieved. A cationic iridium complex, having a chiral diene ligand, and an isoquinolyl moiety as a directing group are essential for regioselective and enantioselective CHbond activation.

ortho-Amidation of 2-pyridinyl ferrocenes with 1,4,2-dioxazol-5-ones was achieved via Cp*Co(III)-catalyzed direct C-H bond functionalization reaction. In the presence of Cp*Co(CO)I-2, in combination with AgPF6 and AgOPiv, a wide range of ferrocene-based amidated products were obtained in up to 96% yield under mild reaction conditions. A gram-scale reaction proceeded smoothly with high efficiency. Isoquinoline and pyrimidine are also suitable directing groups in this transformation. (C) 2018 Elsevier Inc. All rights reserved.
