10. Since the olefin dynamic behavior has been investigated through NMR spectroscopy, henceforth a process which is slow (or fast) on the NMR time scale will be simply indicated as slow (or fast).
11. 5 A possible explanation of the high symmetry displayed by the complexes may be given by admitting that the electronic properties of the electron-poor alkene allow the occurrence of a fast dissociative/associative equilibrium.

15. 13C NMR spectra are fully consistent with them.
16. Traces of free olefin may be generated after dissolution of the complexes, either by dissociation or by an associative process involving the solvent.
