    • This is not a trivial choice since, at lower temperatures, one begins to observe restricted rotation around the various C-C and, for the SimplePhos, 3, P-C bonds, with the resultant loss of resolution and spectral clarity. At higher temperatures, the dynamics of olefin exchange dominate. Consequently, the temperatures indicated represent the most reasonable compromise possible. On the basis of the observed temperature-dependent line shapes we estimate an activation energy of ca 10-13 kcal mol-1
