Abstract
3He NMR spectroscopy has been used to study the equilibria of Diels-Alder additions of 9,10-dimethyl anthracene (DMA) to (3)He@C(60) and (3)He@C(70). Spectra of a series of equilibrium mixtures showed peaks for the isomeric adducts. One monoadduct, six bis-adducts, eleven tris-adducts, and ten tetrakis-adducts of DMA to C(60) were seen. One monoadduct and three bis-adducts of C(70) were detected. Equilibrium constants were found for these reactions and values for DeltaG, DeltaH, and DeltaS were obtained.Entities:
