IN view of the interest now manifested in organic derivatives of antimony, we desire to place on record our discovery of the antimonial analogues of the cacodyl series on which we have been engaged during the last three years.
Dialkylstibylsodium compounds have been prepared by cleavage of trialkylstibines with sodium in liquid ammonia. Reactions of the latter with epoxides, N-benzoylethylenimine and β-propiolactone have afforded several new functionally substituted organostibines. The different reactivities towards such cleavage of different alkly groups bound to antimony opens a route to the synthesis of asymmetrically

The syntheses and spectroscopic (NMR, MS) investigations of the antimonates [Ph4P]+[Me2SbCl4]− (1), [Me4Sb]+[Me2SbCl4]− (2), [Et4N]+[Ph2SbCl4]− (3), [Bu4N]+[Ph2SbCl4]− (4), [Me4Sb]+[Ph2SbCl4]− (5), [Et3MeSb]+[Ph2SbCl4]− (6), [Et4N]+[Ph2SbF4]− (7) and [Et4N]+[Ph2SbBr4]− (8) are reported. Halogen scrambling reactions of Et4NBr or Ph4EBr (E = P, Sb) with R2SbCl3 (R = Me, Ph) produce mixtures of compounds

[nBu4N][nBu2SbCl4] (1) is synthesized by reaction of nBu4NCl and nBu2SbCl3. [Et3SbMe]2- [(MeSbCl3)2] (2) is formed from [Et3SbMe]I and Me2SbCl3. The structures of 1 and 2 were determined by single-crystal X-ray diffractommetry.

The reactions of the organotin chlorides RnSnCl4−n(R = Me or Ph; ⩽ n ⩽ 4) with the Lewis acids SbCl5 and BCl3 have been investigated by 119Sn and (where appropriate) 11B NMR spectroscopy. The results show that transfer of organo-groups to antimony or boron usually takes place rather than chloride abstraction to give cationic tin(IV) species, and this process is more facile for phenyl than methyl groups
