Basic Ionic Liquid-Catalyzed One-Pot Synthesis of the Spiroacenaphthylene Derivatives in Water Medium
摘要:
The basic ionic liquid (benzyl)(dimethyl)(N,N-dimethylaminoethyl)ammonium chloride was found to be an efficient and reusable catalyst for the synthesis of spiroacenaphthylenes via the multicomponent reaction between acenaphthenequinone, malononitrile and alpha-methylenecarbonyl compounds (beta-diketones, pyrazolones) in water.
