Procedure

Approximately 0.6 g of SALEN ligand dissolved in 1 ml water was loaded into each reactor tube of the Multiclave™, and 5 ml of 4:1 (weight ratio) water/EO was added at 100° C. The reactor was blanketed with 250 psig of N2. The experiment with the same SALEN ligand dissolved in 5 ml of water and treated with carbon dioxide over the weekend at room temperature was repeated but with 250 psig of CO2 as blanket gas.
