摘要: We present the chemo-, regio-, and stereoselective synthesis of vinyl chalcogenide compounds promoted by organylzinc chalcogenolates. In this protocol, reductive cleavage diorganyl dichalcogenide bonds Zn/NH4OH system led to The reaction was performed with propiolic acids esters afforded β-organochalcogenacrylic under mild basic conditions. stereochemistry corresponded anti-Markovnikov addition organyl chalcogenolate constituents across triple bond.
