Cpds. are of formula: R1R2R3MSA (where M = Sn or Pb, R1-R3 are 1-16C linear or branched aliphatic residue opt. contg. a double bond, cyclohexyl, cyclopentyl, or Ph, while R1+R2+R3 contain is not >18C, and A = a strongly hydrophilic residue contg. a polyol, polyether, carboxylic ester, amide, or salt, sulphonate, and/or ammonium salt functions) and may be prepd. by condensing R1R2R3MX (where X = OH, 1/2(O), Cl, Br, I or OAc) with HSA, in the presence of a base. |
