- Organoantimony Derivatives of 2,4,6-Tribromophenol
-
2,4,6-Tribromophenoxytetraphenylantimony was prepared in 93% yield by the reaction of pentaphenylantimony with bis(2,4,6-tribromophenoxy) triphenylantimony Ph3Sb(OC6H2Br 3-2,4,6)2 in toluene at 90°C (1 h). Bis(2,4,6-tribromophenoxy)triphenylantimony, in turn, was prepared by oxidation of triphenylstibine with hydrogen peroxide in the presence of 2,4,6-tribromophenol in ether at 20°C (12 h) in 47% yield, with the second reaction product being μ-oxobis[(2,4,6-tribromophenoxy)triphenylantimony] in which the antimony atom, according to single crystal X-ray diffraction, has a trigonal bipyramidal surrounding with the bridging oxygen atom and 2,4,6-tribromophenoxy substituents in the axial positions.
