Treatment of a Thallium(I) carboxylate with 1 molar equivalent of bromine gives the corresponding thallium(III) carboxylate dibromide. High yields of primary alkyl bromides are obtained if the thallium(III) carboxylate dibromide is treated with 0.5 mol equiv. of bromine in refluxing carbon tetrachloride. Pyrolysis of the thallium(III) derivative in the absence of added bromine gives a low yield of
用1摩尔当量的溴处理羧酸hall(I),得到相应的羧酸((III)二溴化物。如果将0.5 (III)羧酸盐二溴化物用0.5摩尔当量处理,则可获得高收率的伯烷基溴化物。回流四氯化碳中的溴。在没有添加溴的情况下of (III)衍生物的热解产生相应烷基溴的低产率。羧酸hall(I)以高产率用于制备烷基溴的用途限于伯羧酸的盐。从使用铊羧酸的烷基溴化物的制备一个简单的程序(我)碳酸盐已被开发出来。
