Synthesis of Boron-Iodinated <i>o</i>-Carborane Derivatives. Water Stability of the Periodinated Monoprotic Salt

Boron periodination of o-carborane has been achieved by taking account of the fact that B atoms in the cluster are of two types, i.e., those adjacent to both C atoms and the remainder. The high number of nonequivalent leaving groups opens the possibility through B−C coupling to materials with novel possibilities and to self-assembling due to the enhanced polarizability of the C−H bond. Periodination has accentuated the acidity of the carborane, and monoprotic salts are stable in water.
