Synthesis of boron-iodinated o-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.
