1.3- Dimethylimidazolium iodide, formation

Normally acylation reactions would be considered standard chemistry but replacing an aryl bromide with a ketone under relatively mild conditions warrants attention. Here 23 is treated with 1,3-dimethylimidazolium iodide (1,3-dii) in refluxing THE leading to the formation of the ketone 24 (Equation 8) <1997H(45)2159>.
