For example, in B.V. Depamphilis et al. Synthetic analogs of the active sites of iron-sulfur proteins.VI. Spectral and redox characteristics of the tetranuclear clusters [Fe 4 S 4 (SR) 4 ] 2- (J.Am.Chem.Soc.1974,26,4159-4161) discloses a kind of sulfur-containing compound 4-trimethylammonium thiophenol hexafluorophosphate and its synthetic method, 4-trimethylammonium thiophenol Hexafluorophosphate is an amphoteric sulfur-containing compound that can be used in the synthesis of multinuclear polymers and clusters, but it is insoluble in water. In fact, most sulfur-containing compounds can only be dissolved in organic reagents, which will inevitably cause a large amount of Loss of organic reagents and environmental pollution
After searching the literature, no ideal amphoteric sulfur-containing compounds have been found so far

Abstract

A S-contained amphoteric compound containing the cation of quaternary ammonium salt and the anion of benzenethiol is prepared through dissolving 4-trimethylamine benzenethiol hexafluorophosphate in organic solvent, dropping triethylamine to generate white deposit, reaction filtering, and washing to obtain white powder used as S-contained ligand.

Description

technical field [0001] The invention relates to an amphoteric sulfur-containing compound and a preparation method thereof, and also relates to the use of the amphoteric sulfur-containing compound in the synthesis of metal complexes, clusters and polymers. Background technique [0002] Amphoteric sulfur-containing compounds react with metal ions to form a series of very interesting multinuclear polymers and clusters, and studies have shown that such clusters have certain application prospects in biopharmaceuticals. For example: in Preparation of complexes of the 3-trimethylammonio-1-propanathiolato ligand[M{S(CH 2 ) 3 NMe 3} 2 ](PF 6 ) 2 , M=Zn, Cd, Hg. CrystalStructures of monomeric and polymeric forms of the mercury complex (Inorg. Chim. Acta 1991, 184, 167-175) reported that mercury (II) compounds react with amphoteric sulfur-containing compounds to form Triphenylphosphine gold(I) complexes of sterically demanding and nondemanding arenethiols....
