Electrosynthesis of 3-thienylzinc bromide from 3-bromothiophene via a nickel catalysis

Article abstract of DOI:10.1016/S0040-4039(97)00259-1

3-Thienylzinc bromide is prepared under mild conditions by electroreduction of a DMF solution of 3-bromothiophene, zinc bromide, and a catalytic amount of nickel-bipyridine complex using a magnesium rod as sacrificial anode. The resulting organometallic is then coupled with aryl halides using a palladium catalysis.
