Halogen Exchange Between Aryl Grignarg Reagents and Aryl Halides in the Presence of Nickel(II) Chloride
A unique halogen exchange reaction between aryl Grignard reagents and aryl halides, which occured during an attempted cross-coupling reaction using non-ligated nickel(II) chloride as a catalyst, has been observed.The halogen exchange takes place between arylmagnesium iodides and aryl bromides but not between arylmagnesium bromides and aryl chlorides.

One Pot Synthesis of p-Polyphenyls via the Intramolecular Cyclization of 3-Dimethylaminohex-5-en-1-ynes
Para linked polyphenyls of various molecular weights are conveniently synthesized from p-bis(3-dimethylamino-1-propynyl)arenes and 1-aryl-2-propenyl bromides in moderate yields using a three step, one-pot procedure.
