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

Integrated electrochemical reactors in automated flow systems have been utilised for chalcogenophosphite formations. Multiple electrochemical reactions can be performed using a programmed sequence in a fully autonomous way. Differently functionalised chalcogenophosphites have been efficiently synthesised in short reaction times.
