Organobismuthanes undergo dismutation, a substituent scrambling process, complicating the synthesis of unsymmetrically trisubstituted bismuthanes of the general formula Ar12Ar2Bi. Although the dismutation is a mechanistically diverse phenomenon, at ambient or lower temperatures, dismutation is triggered mainly by an electrophilic bismuth source. Therefore, the selection of the electrophile, Ar12BiX (X = tosylate or iodide if Ar1 = mesityl) or Ar1BiX2 (X = tosylate), and its use in low concentration during the reaction is key to suppressing the dismutation, leading to new, streamlined protocols utilizing direct arylations of Ar12BiX (X = OTs or I) or Ar1Bi(OTs)2 with organozincs affording heteroleptic triarylbismuthanes Ar12Ar2Bi.

Reactions of tetra- and triphenylantimony halides with phenylbismuth bis(2,5-dimethylbenzene)- and bis(4-methylbenzene)sulfonates in a benzene-ether solution at room temperature were used to prepare tetraphenylantimony bis[μ-(2,5-dimethylbenzenesufonato)]-bis[dichloro(phenyl)bismate(III)] (Ph4Sb+)2 · [Ph2Bi2(OSO2C6H3Me 2-2,5)2Cl4]2-, tetraphenylantimony bis[μ-(4-methylbenzenesulfonato)]-bis[chloro-(4-methylbenzenesulfonato) phenylbismate(III)] [Ph4Sb+]2[Ph2Bi2(OSO 2C6H4Me-4)4Cl2] 2- · 2C6H5, and tetraphenylantimony bis[μ-(4-methylbenzenesulfonato)]bis[bromo(4-methylbenzenesulfonato) phenylbismate(III)] [Ph4Sb+]2[Ph2Bi2(OSO 2C6H4Me-4)4Br2] 2- · 2C6H6. The structure of these ionic compounds was established by X-ray diffraction. The cation in all the compounds is (Ph4Sb)+, and in the double-charged cyclic anions the arenesulfonic group plays the role of a bridging ligand between the two bismuth-containing fragments.
