Electrochemical selenation of phosphonates and phosphine oxides

An environmentally friendly electrocatalytic strategy for the synthesis of organoselenophospho-rus between phosphonates /phosphine oxides and selenols/diselenides is reported. The reaction was performed with metal-, base- and oxidant-free at room temperature, and affords the selenophosphorus products in good to excellent yields. The good tolerance of substituents enables the reaction more attractive in the preparation of organoselenophosphorus compounds. (C) 2019 Published by Elsevier Ltd.
