Title:
METHOD FOR PREPARATION OF CARBORANE ANIONS
Document Type and Number:
WIPO Patent Application WO2002079210
Kind Code:
A3
Abstract:
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.
