Reaction of Pentaphenylantimony with Triphenylbismuth Diacylates

摘要

Reactions of pentaphenylantimony with triphenylbismuth diacylates yield the corresponding tetraphenylantimony acylates. Triphenylbismuth bis(trichloroacetate) was prepared by oxidation of triphenylbismuth with hydrogen peroxide in the presence of trichloroacetic acid. The structure of tripyhenylbismuth dibenzoate was determined by single crsytal X-ray diffraction. The coordination polyhedron of the central atom is intermediate between trigonal bipyramid and pentagonal bipyramid; the benzoate groups occupy the equatorial position.
