ABSTRACT:
A highly selective method is disclosed for cleaving carboranyl carbon-silicon bonds which comprises contacting either silylated monomeric carboranes or polymers thereof with a nucleophilic cleavage agent and, if desired, in the presence of a protic reagent and recovering the carborane cage intact. This technique is employed in a method for producing the useful meta-carborane in bulk which includes the steps of isomerizing a silylated derivative of ortho-carborane using known techniques to produce the corresponding meta-carborane derivative and then cleaving the carboranyl carbon-silicon bond to form meta-carborane.
