DOI: 10.1021/acs.orglett.2c03894

Abstract: The construction of molecular skeletons and modification of molecules using widely available and easily prepared alcohols as radical precursors for coupling reactions are significant and challenging subjects. We herein report a straightforward strategy for the… read more here.

Published in 2022 at "Journal of the American Chemical Society"

DOI: 10.1021/jacs.2c00527

Abstract: We demonstrate Markovnikov hydroalkoxylation of unactivated alkenes using alcohols through a triple catalysis consisting of photoredox, cobalt, and Brønsted acid catalysts under visible light irradiation. The triple catalysis realizes three key elementary steps in a… read more here.

Published in 2022 at "Chemical communications"

DOI: 10.1039/d2cc03595b

Abstract: An enantioselective ortho-C(sp2)-H functionalization of ketones with 1,6-enynes is demonstrated via photoredox/cobalt dual catalysis. The method exhibits high yields, functional group tolerance, and selectivity. Mechanistic studies suggested the operation of visible-light mediated low-valent cobalt complex… read more here.
