Triorganostibine Sulfide

In contrast to the well-studied triorganophosphine oxide or sulfide, very little work had been done on the analogous organoantimony compounds. 

4 Recently two configurational isomers have been isolated from dimethyltin N,N -bis(salicylaldehyde)ethylenediiminate (23). 

The UV spectra of trimethyl- and tricyclohexylstibine sulfides have absorption maxima at ca. 280 nm in n-hexane which give a blue shift in acetonitrile, as shown in Fig. 4. These bands may be assigned to intra-

This result is particularly interesting since no reaction occurred when such ditins were heated with elemental sulfur under similar conditions. The enhanced reactivity of the triorganostibine sulfide in these reactions may be attributed to the semipolar Sb—S bond.
