Abstract
A unique halogen exchange reaction between aryl Grignard reagents and aryl halides, which occurred during an attempted cross-coupling reacti on using non-ligated nickel(II) chloride as a catalyst, has been obser ved. The halogen exchange takes place between arylmagnesium iodides an d aryl bromides but not between arylmagnesium bromides and aryl chlori des.
