ÉÉÉÉÉÉÉÉÉ! ΩCpRe COfi2 cyclopentanefiä 1fi assigned to the protons of the bound methylene unit. The fact that a single resonance is observed, coupled with a highly shielded 13C resonance and a large equilibrium isotope shift accompanying deuterium incorporation,[3c] suggests a fast exchange between two equivalent complexes in which one of the C¿ H bonds in this methylene unit is complexed with the metal center. A rapid, ...
