Photocycloadditions of ptcridinc-L4,7-triones to alkenes are describcd. Irradiation of the pteridine-2,4,7-triones I ab in the prescncc of electron-deficient and neutral alkenes 2 gave the azetidines 3-11 through [ 2 + 5 ] cycloaddition reaction of the carbonnitrogen double bond of the ptcridine-2,4

We describe the HPLC separation and identification of N@C60 and N2@C60. These species were observed after eleven sequential HPLC separations. Their retention times are in the same range as those of the other noninteractive endohedral species of C60, such as noble gas endohedral C60. The separation f
