Fig. 1. Synthesis and reaction of rhodium alkoxo alkene complexes 3a–m. Rate constants refer to the reaction of alkoxo–alkene complexes 3a–m at 35 °C in tol-d8 with 20 equiv. of added PPh3. Bite angles are those from published work.37,38 Yields were determined by 1H NMR spectroscopy using 1,3,5-trimethoxybenzene (TMB) as internal standard. aTHF-d8 used as solvent; b0 °C was used as the reaction temperature.
