[60]Fullerene
derivatives with novel 1,4,9,25- and 1,4,9,12-configurations were
obtained by reactions of C60 with aliphatic ketones and
benzyl bromide under basic conditions. The structures of the products
were determined by X-ray single-crystal diffraction and spectroscopic
characterization. The reactions were rationalized by a monoenolate
addition experiment and in situ vis–NIR spectroscopy.
