The action of alkyl halides on esters of antimonous and thioantimonous acids

Abstract

1. Alkyl halides react with esters of antimonous acid with cleavage of ethers and formation of dialkoxyhalostibines. In this ways the preparation was effected of diethoxy-, dibutoxy-, diisoamyloxybromostibines and of diethoxy-, dibutoxy- and diisoamyloxyiodostibines. 2. Reaction of alkylchloromethyl ethers with antimonous esters leads to separation of the corresponding formals and to formation of alkoxychlorostibines. (RO)3Sb + CH2Cl-OR??? → (RO)2SbCl + ROCH2OR??? (RO)2SbCl + CH2Cl-OR??? → (RO)SbCl2 + ROCH2OR??? 3. Alkyl halides readily react with esters of trithioantimonous acid to for dialkyl sulfide and to haloanhydrides of dithioantimonites. The bromoanhydride of diethyl dithioantimonite and the corresponding iodoanhydride were prepared. © 1954 Consultants Bureau, Inc.
