STUDIES ON SYNTHETIC AND STRUCTURAL ASPECTS OF UNSYMMETRICAL TETRAORGANOARSONIUM AND STIBONIUM HALIDES, PSEUDOHALIDES AND CARBOXYLATES - ELECTROPHILIC CLEAVAGE OF M-ALLYL BOND

Triphenylarsine and: triphenylstibine react with allyl bromide to give the corresponding allyltriphenylarsonium and stibonium halides. The m etal-allyl bond is readily cleaved by electrophiles, such as Br-2, I-2 , ICl and IBr. Metathetical reactions involving allyltriphenylarsonium and stibonium halides and the appropriate metal salts, M'X (M' = Ne, K, Ag; X = NCS, NCO, N-3, CW3COO, CCl3COO, C6H5COO) have been employed to yield a series of ne tv compounds. The compounds are monomeric in benzene solution and 1 : 1 electrolyte in nitromethane.
