New Synthesis of Diselenophosphinates of Heavy Metals

摘要

The four-component reaction between secondary phosphines R2PH (R = arylalkyl, hetarylalkyl), elemental selenium, diethylamine, and heavy metal acetates M(OAc)_n (M = Ni, Zn, Cd, Sn, Hg, Pb, Bi) proceeds under mild conditions (22-55°C, 0.5 h, EtOH) with the formation of the corresponding diselenophosphinates M(Se2PR2)_n in 55-90% yield.
