chalcogenide compounds promoted by organylzinc chalcogenolates. In this protocol, reductive cleavage of diorganyl dichalcogenide bonds by the Zn/NH4OH system led to organylzinc chalcogenolates. The reaction was performed with propiolic acids and esters and afforded β-organochalcogenacrylic acids and esters under mild basic conditions. The stereochemistry corresponded to anti-Markovnikov addition of the organyl
