22. Typical experimental procedure for the reuse of catalyst: After the reaction was completed, the mixture of reaction was diluted with water, and then the organic species were extracted with ether. The catalyst remaining in the aqueous layer can be recovered by removing water and then drying under vacuum at 200 °C for 4 h for the next use.
