First synthesis of a new fullerene oximes bis(9-[hydroxo]-1-[1′-hydroxymino-2′-oxo-2′-alkyl-ethyl])1,9-dihydro-[C60-Ih][5,6]fullerenes via reaction of C60 with ketones and NaNO2 promoted by HCl

ABSTRACTA mixture of cis-2 and cis-3 isomers of new fullerene derivatives bis(9-[hydroxo]-1-[1′-hydroxymino-2′-oxo-2′-alkyl-ethyl])-1,9-dihydro-[C60-Ih][5,6]fullerenes have been selectively synthesized with high yields at the reaction of C60 fullerene with ketones Me2CO, EtMeCO, i-PrMeCO, PhMeCO in the presence of NaNO2 and HCl.
