Stoichiometric kinetics for the cross-coupling reaction. (a) Correlation between reaction rate by monitoring loss of oxoCr(V) salen and concentration of Cr(V) (0.125, 0.0875, 0.0625, and 0.0375 mM) using an excess of 7 and 8 (2.5 mM). (b) Correlation between reaction rate by monitoring loss of oxo-Cr(V) salen and concentration of 8 (0.25, 0.175, and 0.125 mM) with excess 7 (2.5 mM) and Cr(V) (0.25 mM). (c) Correlation between reaction rate from GC measurements and concentration of 7 (0.41, 0.82, and 1.65 mM) using an excess of 8 (4.1 mM) and Cr(V) (0.41 mM).
