Preparing closo-boranate, useful e.g. to prepare carborane, comprises deprotonating borate ion under basic conditions to obtain deprotonated borate ion and converting the borate ion and/or deprotonated borate ions using oxidizing agent

摘要

Preparing closo-boranate (I), comprises deprotonating borate ion (II) under basic conditions to obtain deprotonated borate ion (III) and converting (III) and/or (II) under the addition of oxidizing agent. Preparing closo-boranate (I) of formula ([B 1 0H 1 0] 2 -) (Ia) and/or ([B 1 1H 1 1] 2 -) (Ib), comprises deprotonating borate ion of formula ([B 1 1H 1 4] -) (II) under basic conditions to obtain deprotonated borate ion of formula ([B 1 1H 1 3] 2 -) (III) and converting (III) and/or (II) under the addition of oxidizing agent.
