Notes:
Tri- and diphenyllead(IV) diorganophosphinodithioates, PhnPb(S2PR2)4-n (n = 2 and 3; R = Me, Et, Ph) were prepared by reacting the corresponding organolead(IV) chloride with the sodium or ammonium salt of the phosphinodithioic acid. The title compounds were investigated by infrared, 1H and 31P NMR, and mass spectroscopy, and possible structures were proposed. The diphenyllead(IV) phosphinodithioates, Ph2Pb(S2PR2)2, undergo decomposition on standing or on moderate heating, the least stable being the ethyl derivative. The process was monitored by using 1H and 31P NMR spectroscopy, and a reaction pathway leading to Ph3PbS2PR2, Pb(S2PR2)2, and R2P(S)SPh was established.
