Simple and scalable synthesis of the carborane anion CB11H12

Author affiliations

Abstract

We report a method to obtain carba-closo-dodecaborate anion CB11H12 from boron cluster B11H14 in up to 95% yield using difluorocarbene to complete the carborane cluster. Difluorocarbene itself comes from readily available Ruppert–Prakash reagent CF3SiMe3. The synthesis is straightforward to carry out in heavy wall glass pressure tubes without the need for a glove-box and is easily scalable to 15 g scale.
