    • This invention relates to an improved method for making unsubstituted carborane anions and monosubstituted carborane anions of formula: (R—CBn—Hm′)− where n is an integer ranging from 5 to about 11 and m′ is an integer ranging from 5 to 16 where the relative values of n and m′ depend upon the exact structure of the carborane and the presence of a non-hydrogen substituent. m as used herein is an integer ranging from 5 to 16. When R is hydrogen the anion is unsubstituted. When R is a halogen, a phenyl, a substituted phenyl group, such as fluorophenyl group, or any other substituent, the carborane is substituted. The method is particularly useful for preparation of twelve-vertex carborane anions R—CB11H11−, where R is a defined above, and is specifically useful for preparation of the unsubstituted carborane CB11H12-??, where R is H.
    • 本发明涉及一种制备未取代的碳硼烷阴离子和具有下式的单取代的碳硼烷阴离子的改进方法:(R-CB N-H) - H SUP >其中n是5至约11的整数,m'是5至16的整数,其中n和m'的相对值取决于碳硼烷的精确结构和非氢取代基的存在。 m为5〜16的整数。当R为氢时,阴离子为未取代的。 当R是卤素时,苯基,取代的苯基,例如氟苯基或任何其它取代基,碳硼烷被取代。 该方法对于制备十二个顶点碳硼烷阴离子R-CB 11,其中R为上述定义,特别有用,以及 特别适用于制备未取代的碳硼烷CB 11 H 12 -12,其中R为H.
