Base-Promoted Reactions of Organostibines with Alkynes and Organic Halides to Give Chalcogenated (Z)-Olefins and Ethers

Organic Letters, Год журнала: 2022, Номер 24(33), С. 6159 - 6164

Опубликована: Авг. 16, 2022

Herein, with air-stable chalcogenated stibines (Sb-ER) as organometallic chalcogenating reagents, we developed base-promoted (Z)-hydrochalcogenation of alkynes DMSO/DMSO-d6 hydrogen/deuterium sources, giving (Z)-olefins in good yields and excellent regioselectivity. These easily synthesized from halostibines situ generated [Zn(ER)2] at room temperature within a few minutes, could be also used the C(sp3)-S(Se) cross-coupling C(sp3)-X copper-catalyzed C(sp2)-S(Se) C(sp2)-X (X = F, CI, Br, I) under mild conditions. This protocol simply extended to organobismuth complexes (Bi-ER) functional tolerance.
