New ' Bucky- ligands'. Potentially Monoanionic Terdentate Diamino Aryl Pincer Ligands Anchored to C60

Abstract

Two new methanofullerenes have been prepared by the reaction of C{6}{0} with diazo substituted, potentially monoanionic, terdentate diamino aryl ligands, yielding a mixture of the open valence [5, 6]- and closed valence [6,6]-isomers. Single isomers of the pure [6,6]-methanofullerenes were obtained by heating these mixtures in toluene solution.
