14 For sake of consistency, the partial order in 1a was also
measured at 25°C. It is even lower than at 90°C (1.33 vs
1.46), in line with an increase of the dimer to monomer ratio
for entropic reasons.
15 The progress of the reaction was followed by 1H NMR
spectroscopy by integrating the resonance signal of the
