Mr. Banks et al., AZIRIDINO[2',3' 1,6][60]FULLERENE - ISOLATION OF THE FIRST CLOSED [5,6]-BRIDGED FULLERENE ADDUCT/, Journal of the Chemical Society, Chemical Communications, (8), 1995, pp. 887-888
In addition to the expected formation of closed [6,6]-bridged aziridin
ofullerene 3 by reaction of [60]fullerene with singlet oxycarbonylnitr
enes, small amounts (ca. 10%) of previously undetected closed [5,6]-ad
ducts 5 have been isolated, and are thought to arise by trapping of tr
iplet nitrenes.
