Alkali metal diselenophosphinates R¹ 2PSe2M (R¹ = aryl, arylalkyl, hetarylalkyl; M = Na, K, or Cs) readily react with organic halides R²Hal (R² = alkyl, allyl, propargyl, benzyl; Hal = Cl, Br, or I) under mild conditions (EtOH, 50-55 ˚C, 30 min) to afford the corresponding Se-esters of diselenophosphinic acids R¹ 2P(Se)SeR² in high yields (77-95%). diselenophosphinates - organic halides - esters -
