A new method for synthesis of tetraphenylbismuth arenesulfonates Ph4BiOSO2Ar, Ar = C10H15O, C10H7-1, C6H4(COOH-2)

Reaction of equimolar amounts of 2,4,6-tribromophenoxytetraphenylbismuth (synthesized from pentaphenylbismuth and 2,4,6-tribromophenol) with camphor-10-sulfonic, 1-naphthalene sulfonic, and 2-sulfobenzoic acids in an acetone/water mixture synthesized tetraphenylbismuthonium arenesulfonates Ph4BiOSO2C10H15O∙H2O (1), Ph4BiOSO2(C10H7-1)∙H2O (2), [Ph4Bi]+[OSO2C6H4(COOH-2)]- (3), two of which were hydrates of tetraphenylbismuth arenesulfonates. The melting points and IR spectra of the resulting compounds coincided with similar characteristics of complexes obtained from pentaphenylbismuth and arenesulfonic acids.
