Arrhenius‐plot for the estimation of the activation energy E a of the conversion of epoxide 1 a with CO2 in the presence of catalyst 8 over the temperature range of 35–65 °C (T=308.15–338.15 K). Reaction conditions: 1,2‐butylene oxide (1 a, 460 mmol), 2 mol % catalyst 8, p(CO2)=1.0 MPa. y=−476.5x+13.277, R 2=0.9638.
