Реакции дефенилирования пентафенилсурьмы дикарбоновыми кислотами

Abstract

It has been founded that the interactions of pentaphenylantimony with tetrachlorophthalic, tetrafluorophthalic, ferrocenodicapboxylic acids in toluene lead to the formation of bis (tetraphenylantimony) carboxylates regardless of the mole ratio. The products of the reactions between pentaphenylantimony and succinic acid are tetraphenylantimony hydrogen succinate (mole ratio 1:1, dioxane) or bis(tetraphenylantimony) succinate (2:1, toluene). Bis(tetraphenylantimony) carboxylates was obtained by interaction of pentaphenylantimony with carboranedicarboxylic and acetylenedicarboxylic acids. However by the mole ratio 1:1 on of the carboxyl groups is decarboxylated and tetaphenylantimony propiolate and carboranecarboxylate were obtained. The reaction of pentaphenylantimony with oxalic acid (2:1 mol, 2 h, 90 °С) in dioxane has led to the formation of bis(tetraphenylantimony) oxalate dioxane solvate. The structure of the synthesized compounds was determined by the X-ray analysis.
