Exchange rates in cyclohexylamine‐ N ‐ 3 H catalyzed by cesium cyclohexylamide were determined by 3 H NMR for the vinyl positions of 3,3‐dimethyl‐l‐butene (1‐ trans >1‐ cis >2‐) and the cyclopropyl methylene positions of norcarane ( exo > endo ) relative to the ring position of p ‐xylene. The kinetic acidity of cubane was confirmed. © 1998 John Wiley & Sons, Ltd.
