    • Grubbs and co-workers used a DANTE pulse sequence and a CIFIT program to extract exchange rate constants, and reported the data per coordinated phosphine (see ref 12). Using this methodology, an exchange value of 0.381 at 50°C using 3 equiv of phosphine was obtained.

    • note
    • Because the NMR pulse sequences used by Grubbs and ourselves for measuring phosphine exchange rates were not the same (see ref 13), a direct comparison between the two sets of results is not possible.
