Characteristic Features of the Reactions of Triarylantimony with Hydroxybenzoic Acids. Structure of the Reaction Products.

Tri(meta-tolyl)antimony and triphenylantimony react with 2,6-dihydroxybenzoic and 3,5-dinitrosalicyclic acids in the presence of hydrogen peroxide to give triarylantimony dicarboxylates (I and II∙2PhH, respectively). The reaction of tris(5-bromo-2-methoxyphenyl)antimony with 2,6-dihydroxybenzoic acid gives binuclear organoantimony compound with a bridging oxygen atom (III∙MeCN). The structures of the products were determined by X-ray diffraction (CCDC nos. 1911551, 2117678, 1970910). [ABSTRACT FROM AUTHOR]
