A method for obtaining perchlorinated di-,-substituted derivatives of the -decaborate anion with various alkyl groups has been developed: [BClSR] (R= -CH, -CH, -CH, -CH, -CH, -CH, CHPh, and -S(CH)). The method is based on the preparation of the sulfonium-substituted anion [BHSR] by alkylation of the anion [BHSH] with bromoalkanes (-CHBr, -CHBr, -CHBr, -CHBr, -CHBr, -CHBr, PhCHBr, and BrCH(CH)CHBr) followed by the cluster chlorination with sulfuryl chloride SOCl in acetonitrile. The process proceeds until the hydrogen atoms in the boron cluster are completely replaced with chlorine and completes within 60 h. It has been found that the melting point of salts ((CH)N)[BClSR] (R= -CH, -CH, -CH, -CH, -CH, and -CH) strongly depends on the length of the hydrocarbon chain of the substituent R.
已开发出一种获得具有各种烷基的十硼酸盐阴离子的全氯代二 - ， - 取代衍生物的方法：[BClSR]（R = -CH、-CH、-CH、-CH、-CH、-CH、CHPh和 -S(CH)）。该方法基于通过用溴代烷烃（-CHBr、-CHBr、-CHBr、-CHBr、-CHBr、-CHBr、PhCHBr和BrCH(CH)CHBr）将阴离子[BHSH]烷基化来制备锍取代的阴离子[BHSR]，然后在乙腈中用硫酰氯SOCl进行簇氯化。该过程一直进行到硼簇中的氢原子完全被氯取代，并在60小时内完成。已发现盐((CH)N)[BClSR]（R = -CH、-CH、-CH、-CH、-CH和 -CH）的熔点强烈取决于取代基R的烃链长度。
