An efficient, general, and atom-economic synthesis of organoammonium thioselenophosphinates has been developed by exploiting a three-component reaction between secondary phosphine sulfides, elemental selenium, and various amines. The reaction proceeds under mild conditions (70–75 °C, 1 h, EtOH) to afford thioselenophosphinates in 77–94% yields.
