Abstract
Tris(2-methoxyphenyl)antimony and tris(3-fluorophenyl)antimony react with 2,3-dihydroxybenzoic and 3,4-dihydroxybenzoic acids in the presence of tert-butyl hydroperoxide to form carboxycatecholato-О,О'-triarylantimony. Under similar conditions, tris(4-fluorophenyl)antimony reacts with 2,3-dihydroxybenzoic acid to form tris(4-fluorophenyl)antimony dicarboxylate. Structural features of the reaction products are determined by X-ray diffraction (XRD) (CIF files CCDC nos. 2126358 (I), 2124252 (II·H2O·Et2O), 2121839 (III·0.5С6Н6), and 2131083 (IV·2.5С6Н6).
