Abstract

Conclusions There is no substantial secondary kinetic isotope effect for CN rotation in amides, for substitution of deuterium at either carbon or nitrogen. The small effects seen can be attributed to slight changes in zero-point energies of out-of-plane bending modes, rather than conversion of CH or NH bends into the reaction coordinate. The large KIE in ethylenes may be a special case. Formamide may also be a special case for which the thermal ...
