Synthesis of nitriles of the ortho-carborane series and their interaction with enaminonitriles

Article abstract of DOI:10.1007/BF02495704

A new convenient method for the synthesis of o-carborane carbonitriles by dehydration of carborane carboxamides of the corresponding carboxylic acids with trimethylsilyl polyphosphates was elaborated. Acid-catalyzed reactions of o-carborane carbonitriles with enaminonitriles were studied. Thienopyrimidine with a carboranyl substituent was synthesized for the first time.
