Title: Air-stable organoantimony compounds in cross-coupling reactions

Abstract:

Organometallic compounds are widely used coupling reagents, but their limitations, such as sensitivity to air and water, have hindered their further application in highly functionalized complex substrate synthesis. Therefore, the development of new water-resistant and oxygen-resistant organometallic coupling reagents is of great significance. Our research group utilized water-resistant and oxygen-resistant organoantimony chloride as a raw material and synthesized a series of arylstibines, alkynlstibines, alkylstibines, and stibines sulfide compounds through nickel, copper, zinc, and other inexpensive transition metal catalyzed or mediated methods. These synthesized organoantimony compounds were used as coupling reagents, effectively solving the problem of highly selective and efficient synthesis of biphenyl compounds, biphenyl methane derivatives, and diene and triene compounds with similar functional groups and polarities.^[1-5]
