THE EFFECTS OF SOLVENTS ON THE INTRAMOLECULAR PROCESSES------NMR STUDY
摘要:
The influences of methanol-d4(MeOD), dimethylsulfoxide-d6 (Me2SO(D)) and dioxane(C4H8O2) solvents on the intramolecular processes are studied by NMR. It has been shown that the addition of these solvents in CdEGTA complex aqueous solution can increase the rate constant (k) of the nitrogen inversion and decrease the activation energy of this process. The linear relations between In(k) and the reciprocal of the solvent dielectric constants (1/ε) are obtained for all the three solvents.
