Reactions of Triarylbismuth Bis(arenesulfonates)

Reactions of triphenylbismuth with sodium salts, acids, alkalies, and zinc are studied. In the first three cases Bi-O bond cleavage takes place, while zinc reduces the starting bismuth compounds to triphenylbismuth.     

Synthesis and Structure of Tetra- and Triarylantimony Oximates

Pentaphenyl- and penta-p-tolylantimony were reacted with benzophenone oxime or triarylantimony bis(benzophenonoximate) in toluene to obtain tetraarylantimony benzophenonoximate. Triarylantimony bis(benzophenonoximates) were prepared by oxidative addition from tryarylstibine and oxime in ether in the presence of hydrogen peroxide. X-ray diffraction analysis of tetraphenylantimony benzophenonoximate was performed to show that coordination of the antimony atom is trigonal-bipyramidal and the oxime oxygen atom is axial.     

Synthesis and Structure of Tetra- and Triarylantimony Oximates

Reactions of pentaphenyl- and penta-p-tolylantimony with benzophenone oxime or triarylantimony bis(benzophenone oximate) yield tetraarylantimony benzophenone oximates. Triarylantimony bis(benzophenone oximates) were prepared by oxidative addition from triarylstibine and benzophenone oxime in the presence of hydrogen peroxide. X-ray diffraction analysis was performed to show that benzophenone oxime is a dimer and tetraphenylantimony benzophenone oximate has a trigonal bipyramidal antimony atom and an axial oxime oxygen atom.
