Mr. Banks et al., COMPETING PATHWAYS IN THE PHOTOLYTIC CYCLOADDITION REACTIONS OF N-ETHOXYCARBONYLAZEPINE TO [60]FULLERENE - FORMATION OF [2+4] AND [2+6] PHOTOADDUCTS, Journal of the Chemical Society, Chemical Communications, (11), 1995, pp. 1171-1172
The photochemical reaction between [60]fullerene and N-ethoxycarbonyla
zepine, formed in situ by light-induced decomposition of ethyl azidofo
rmate in benzene, produces two photoadducts in the ratio of 4:1 by for
mal [2 + 4] and [2 + 6] cycloaddition reactions as established by a se
ries of high-field (600 MHz) NMR experiments.
