2-Pyridyl and 3-pyridylzinc bromides: direct preparation and coupling reaction

Add time:08/03/2019    Source:sciencedirect.com

A facile synthetic approach to the direct preparation of 2-pyridyl and 3-pyridylzinc bromides has been demonstrated using Rieke zinc with 2-bromopyridine and 3-bromopyridine, respectively. A variety of different electrophiles have been coupled with the resulting organozinc reagents to give the corresponding cross-coupling products in moderate to good yields.
