Aziridino[2′,3′ : 1,6][60]fullerene: isolation of the first closed [5,6]-bridged fullerene adduct

Abstract

In addition to the expected formation of closed [6,6]-bridged azmdinofullerene 3 by reaction of [60]fullerene with singlet oxycarbonylnitrenes, small amounts (ca. 10%) of previously undetected closed [5,6]-adducts 5 have been isolated, and are thought to arise by trapping of triplet nitrenes.
