text: The CH vertices of closo-dicarbadodecaboranes undergo deprotonation upon treatment with organolithium reagents:
  : CBH  +  2 BuLi  →   LiCBH  +  2 BuH
  These dilithiated compounds react with a variety of electrophiles, e.g. chlorophosphines, chlorosilanes, and sulfur.  Many of the same compounds can be produced by hydroboration of alkynes:
  :LiCBH  +  2 RX  →  RCBH  +  2LiX
  :LBH  +  RCR  →  RCBH  +  2L  (L = MeCN, etc.)
  ortho-Carborane can be converted to highly reactive carborynes with the formula BCH.
