Facile Atom-Economic Synthesis of Ammonium Diselenophosphinates via Three-Component Reaction of Secondary Phosphines, Elemental Selenium, and Ammonia

[摘要]：The three-component reaction between secondary phosphines, R2PH [R = Ph(CH2)(2), PhCHMeCH2, PhCH2CHMe, 4-t-BuC6H4(CH2)(2), 4-MeOC6H4(CH2)(2), 2-furyl(CH2)(2), 4-pyridyl(CH2)(2), 6-Me-3-pyridyl(CH2)(2), Ph], elemental selenium, and ammonia proceeds under mild conditions (EtOH-H2O, 53-55 degrees C or EtOH, r.t., 10 min) without the formation of byproducts to give the first representatives of ammonium diselenophosphinates in high yields (up to 96%).
