Investigations on organoantimony compounds. IX. Antimonycarbon bond cleavage in trialkylstibines by sodium in liquid ammonia. Synthetic applications of dialkyl- and diphenylstibylsodium
article
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 substituted organostibines. Tetraalkyldistibines, which are readily available from the 2 1 reaction of dialkylstibylsodium compounds with 1,2-dichloroethane, have been found to be suitable starting materials for the synthesis of hitherto inaccessible chlorodialkylstibines and trichlorodialkylantimony compounds. © 1973.
