4-o-Carboranylpyrylium perchlobates and stable free radicals based on them
The corresponding o-carboranylpyrylium perchlorates were obtained from 4H-pyrans of the o-carborane series under the influence of 70% HClO4 in acetic anhydride or 2,2′,4,4′-tetramethoxydiphenylammonium perchlorate. The carboranylpyranyl free radicals were studied by EPR spectroscopy, and it was shown that the unpaired electron is localized in the carborane ring.
