Oxidative transition-metal-free, cross-coupling reaction between secondary phosphine chalcogenides and alcohols or phenols proceeds in the carbon tetrachoride/triethylamine system under mild conditions (20-52 ˚C, 1-12 h) to give phosphinochalcogenoic O-esters in 70-95% yields. secondary phosphine chalcogenides - alcohols - phenols - phosphinochalcogenoic O-esters
