Published in 2022 at "Organic letters"

DOI: 10.1021/acs.orglett.1c04241

Abstract: An efficient and green electrochemical N-ortho-selective difluoromethylation method of various quinoline and isoquinoline N-oxides has been developed. In this method, sodium difluoromethanesulfinate (HCF2SO2Na) was used as the source of the difluoromethyl moiety, and various N-ortho-selective… read more here.

Published in 2017 at "Organic letters"

DOI: 10.1021/acs.orglett.7b02936

Abstract: An iridium-catalyzed ortho-selective C-H borylation of phenol and aniline derivatives has been successfully developed. Iridium/bipyridine-catalyzed C-H borylation generally occurred at the meta- and para-positions of aromatic substrates. Introduction of an electron-withdrawing substituent on the bipyridine-type… read more here.

Published in 2023 at "Journal of the American Chemical Society"

DOI: 10.1021/jacs.3c02961

Abstract: Dearomative photocycloadditions are valuable chemical transformations, serving as an efficient platform to create three-dimensional molecular complexity. However, the photolability of the original addition product especially within the context of ortho cycloadditions often causes undesired consecutive… read more here.

Published in 2019 at "Chemical communications"

DOI: 10.1039/c9cc02499a

Abstract: Application of an oxidative amination reagent (di-tert-butyldiaziridinone) to the Ru3(CO)12-catalyzed ortho-selective CAr-H amination reaction is described. This strategy shows good functional group compatibility with various phenyl-substituted N-heterocycles, including biologically active substrates, thus providing synthetic potential… read more here.

Published in 2023 at "Molecules"

DOI: 10.3390/molecules28041767

Abstract: The aromatic C(sp2)-H functionalization of unprotected naphthols with α-phenyl-α-diazoesters under mild conditions catalyzed by CuCl and CuCl2 exhibits high efficiency and unique ortho-selectivity. In this study, the combination of density functional theory (DFT) calculations and… read more here.
