Secondary isotope effects on the deslipping reaction of rotaxanes: High-precision measurement of steric size
T. Felder, C. A. Schalley – 2003
A supramolecular measuring instrument for determining steric size: The deslipping reaction of the rotaxane shown with deuterated stopper groups senses the smaller steric size of the deuterium atom and proceeds with a 10?% higher reaction rate than the reaction of the unlabeled rotaxane. This result sheds new light from a supramolecular point of view on the classical problem of determining steric demand.
