Synthesis of 1,2-aceanthrylenedione in the Presence of EmimCl/AlCl3 Ionic Liquid
1.Introduction Aromatic ketones are one of the most important fine chemicals which have been widely used as pharmaceuticals, cosmetics, agrochemicals, dyes and special chemicals1. The Friedel-Crafts acylation reaction is a useful method for the preparation of aromatic ketones and is widely used not only in laboratory scale but also in large scale in industry. The conventional catalyst of Friedel-Crafts is inorganic halid Lewis acid such as AlCl3, BF3, SnCl4 and so on. However, all of the processes have met with some common problems, e.g. Heavy environmental pollution, and troublesome product recovery and purification, and catalysts cannot be reused. Therefore, investigation and development of environmentally friendly catalytic technology have attracted great interest from chemical industry. In recent years, ionic liquids (ILs) have shown great promise as an attractive alternative to conventional catalysts and solvents for synthetic organic chemistry2. But to the best of our knowledge, no articles about acylation of anthracene with oxalyl chloride catalyzed by ILs has been published.
