摘要
A biodegradable functionalized ionic liquid 3-(N,N-dimethyldodecylammonium)propanesulfonic acid hydrogen sulfate ([DDPAR][HSO4]) was prepared and used as a Bronsted acid-surfactant-combined catalyst for the eco-friendly one-pot synthesis of 1,8-dioxo-octahydroxanthenes at 100 degrees C in water. Under these conditions, the reaction of various aromatic aldehydes with dimedone generated 1,8-dioxo-octahydroxanthenes in good yields with a simple postreaction procedure. The products could simply be separated from the catalyst/water system, and the catalyst could be reused at least six times without noticeably decreasing the catalytic activity.
