Aroxytetraaryl antimony compounds. Synthesis, structure, and thermolysis

The reactions of pentaphenylantimony with 3,5-di-tert-butylphenol and of penta-p-tolylantimony with 4,6-dibromo-2-methylphenol in toluene at 20°C were used to prepare Ph4SbOC6H3(t-Bu)2-3,5 and p-Tol4SbOC6H2Me-2,Br2-4,6, respectively. The structures of the products were established by X-ray diffraction analysis. The Sb atoms in the molecules have trigonal-bipyramidal coordination with an axial aroxy group. The Sb-O and C-O were found to depend on the nature of substituent in the aroxy group, and an explanation of this phenomenon was proposed. Thermolysis of (3,5-di-tert-butylphenoxy)tetraphenylantimony at 220°C (1 h) results in quantitative formation of aryl phenyl ether and triphenylstibine. Thermolysis of (2,6-dimethyl-phenoxy)tetraphenylantimony yields triphenylstibine and 2,2′,6,6′-tetramethyldiphenoquinone.
