Popis:	New soluble fullerene derivatives But n C60 were synthesized by the reaction of C60M n (THF) x (M = Li, Na; n = 4, 6, 8, 10, 12) with tert-butyl bromide ButBr. The thus obtained compounds were characterized by spectroscopic methods (IR and NMR spectroscopy), mass spectrometry (MALDI), elemental analysis, and quantum chemical calculations. HPLC was used for chromatographic separation of the products of the reaction of C60Na n (THF) x (n = 4, 6, 8, 12) with ButBr. It was found that But 4C60 and But 6C60 decompose on the column. A complex of physicochemical methods of analysis was used for establishing compositions of individual fractions of chromatographic separation of But 4C60. The structure of one of the components was determined as 1-tert-butyl-1,2-dihydrofullerene 1,2-ButC60H.
