SYNTHESIS OF TETRADECAHYDROUNDECABORATE(-1) FROM BOROHYDRIDE ION

摘要

{PG,1 The tetradecahydroundecaborate({31 1) anion is synthesized from a metal borohydride by heating a suspension of the borohydride ion in a solvent, such as diglyme, with agitation at a temperature of from 85{20 {0 C. to about 135{20 {0 C. and adding an alkyl halide. The B{HD 11{L H{HD 14{HU {31 {L anion obtained is useful in the synthesis of decaborane, an intermediate in formation a carborane-based polymers.
