Synthesis of organoantimony compounds by exchange between organomercury compounds and antimony halides

TLDR: In the reactions of bis-cis-2-chlorovinylmercury with antimony penta-and trichlorides, dichlorotriscis 2-chloro-and dibromo-triscis -2-clovinylantimonys are formed, respectively as mentioned in this paper.

Abstract: 1. In the reactions of bis-cis-2-chlorovinylmercury with antimony penta- and trichlorides, dichlorotris-cis-2-chlorovinylantimony and tris-cis-2-chlorovinylstibine are formed, respectively. The substances described earlier as dichlorotris-cis-2-chlorovinylantimony and tris-cis-2-chlorovinylstibine are the cis-trans-trans isomers. 2. The reactions of tris-cis-2-chlorovinylstibine with chlorine and bromine lead to the formation of dichloro- and dibromo-tris-cis-2-chlorovinylantimonys. 3. The trans isomers of the 2-chlorovinyl compounds of antimony react with liberation of acetylene at a lower concentration of alkali and at a lower temperature than the cis isomers. 4. Exchange reactions between antimony pentachloride and R2Hg provide a convenient method for the synthesis of aliphatic and aromatic compounds of formula R3SbCl2.
