摘要
A thiocarbamate-directed Cp*Co(III)-catalyzed C-H oxidative amidation of olefins is achieved to synthesize a series of enamines. The key feature of this protocol is the use of earth-abundant cobalt as catalyst and thiocarbamate as directing group, which provides an efficient and simple manner to synthesize enamines in good yields with high (Z)-selectivity. This reaction proceeds smoothly under very mild conditions (rt and air), and a wide range of functionalized alkenes, as well as dioxazolones, were compatible with the standard reaction conditions.
