High-pressure Diels–Alder reaction of [60] fullerene with several tropones. Characterization of the 1 : 1-cycloadducts
Abstract
The high-pressure Diels–Alder reaction of fullerite with tropone and several of its derivatives under 300 MPa gave 1 : 1-[4 + 2] cycloadducts of C60 in good yields. Their 1H and 13C NMR spectra were consistent with the structures depicted. These compounds quantitatively regenerate starting materials upon thermolysis.
