First kinetic evidence for the CH/π and π/π solute-solvent interaction of C60 in the Diels-Alder reaction with cyclohexadiene.

The first CH/π solute-solvent interaction of C(60) was evidenced by the kinetic solvent effects in the Diels-Alder reaction with 1,3-cyclohexadiene based on the evaluation of linear free energy relationship of log k(2) with empirical solvent polarity and basicity parameters, E(T)(30) and D(π), respectively.
