2,4-Bis-(4-methoxyphenyl)-1,3,2.5,4.5-dithiadiphosphetane-2,4-disulfide (Lawesson's reagent) reacts with a variety of alcohols and silanols to form dithiophosphonic acids in a facile manner. Their lithium salts react with organotin- and organogermanium chlorides to produce organometallic dithiophosphonate complexes of the type A R-3 "M[S(S)P(R)(OR')] (M = Ge, Sn; R = 4-MeOC6H4; R' = Me, SiPh3, GePh3, SnPh3; R" = Me, Ph) and B R-2 "M[S(S)P(R)(OR')] 2 (M = Ge, Sn; R = 4-MeOC6H4; R' = Me, Et, iPr, tBu, SiPh3; R" = Me, Ph). The ligands in the new organometallic compounds are bound in an asymmetric fashion as revealed by four X-ray structure determinations, containing one representative example of type A and three examples of typeB. All new compounds are fully characterized by analytical and spectroscopic methods.
