Abstract

The iron‐catalyzed homocoupling reaction of aryl Grignard reagent was completed very quickly when the reaction was carried out in a phosphonium salt ionic liquid solvent system at 0°C for 5 min. Using a similar reaction system, the first example of the iron‐catalyzed homocoupling reaction of alkynyl Grignard reagents has also been accomplished using the ionic liquid technology. © 2011 Wiley Periodicals, Inc.
