Four known dithiophosphinic
acids, DTPA, were synthesized and their zinc complexes were prepared as
novelties. The complexes have been proven to have the structures [Zn(µ-DTPAn)2(DTPAn)2],
([DTPAn]= Rn(R)P(S)H, R= 4-CH3O-C6H4-;
R1= iso-amyl-, DTPA1; R2= iso-butyl-,
DTPA2; R3= sec-butyl-, DTPA3; R4=
iso-propyl-, DTPA4). The DTPAs were prepared by the reaction
of the Lawesson
reagent, [2,4–bis(4-methoxyphenyl)–1,3,2,4–ditiyodifosfetan–2,4–disülfür] (LR),
with the corresponding Grignard compounds. The acids formed are viscous liquids
difficult to purify and so they were converted to ammonium salts, [DTPAn][NH4],
which are easy to obtain as pure crystals. The complexes were identified to
have dimeric structures on the basis of mass spectroscopic data.
