Published in 2020 at "Russian Chemical Bulletin"

DOI: 10.1007/s11172-020-2995-0

Abstract: Azo(het)arenes are widely demanded compounds, among which are dyes,1 pharmacologically active substances,2 and energetic compounds.3 Previously, we developed effi cient and environmentally benign syntheses of azo(het)arenes by anodic N—N coupling of aminopyrazoles,4 aminofurazans,5 and aminofuroxans6.… read more here.

Published in 2022 at "Organic letters"

DOI: 10.1021/acs.orglett.2c01954

Abstract: A nickel-catalyzed C-S reductive cross-coupling of alkyl halides with arylthiosilanes for producing alkyl aryl thioethers is developed. This reaction is initiated by umpolung transformations of arylthiosilanes followed by C-S reductive cross-coupling with alkyl halides to… read more here.

Published in 2022 at "Organic letters"

DOI: 10.1021/acs.orglett.2c02454

Abstract: A CuI-catalyzed cross-coupling of alkyl- and phosphorus-centered radicals for C(sp3)-P bond formation is introduced. Diacyl peroxides, generated in situ from aliphatic acids and H2O2, serve as a source for alkyl radicals and also an initiator… read more here.

Published in 2018 at "ACS Catalysis"

DOI: 10.1021/acscatal.8b00420

Abstract: A catalytic protocol for the preparation of α,α-difluoro-β-alkyl-β-ketoamides is developed employing a Pd-mediated carbonylative Suzuki coupling between alkylboron reagents and bromodifluoroacetamides with COgen as the CO source. The reaction reveals good functional group tolerance providing… read more here.

Published in 2017 at "Chemical communications"

DOI: 10.1039/c7cc07151e

Abstract: Single enantiomer molecules are important for the pharmaceutical and agrochemical industries and increasingly so in materials science. Most strategies to obtain enantiomerically enriched molecules rely on either generating new stereogenic centres from prochiral substrates or… read more here.

Published in 2022 at "Chemical Science"

DOI: 10.1039/d1sc06102j

Abstract: The Suzuki–Miyaura cross-coupling of C(sp3)-hybridised boronic compounds still remains a challenging task, thereby hindering the broad application of alkyl boron substrates in carbon–carbon bond-forming reactions. Herein, we developed an NHC/photoredox dual catalytic cross-coupling of alkyl… read more here.
