A cobalt-catalyzed cross-coupling of aryl halides with 2-chloropyrimidines or 2-chloropyrazines is reported in satisfactory to high yields. The key step of this procedure is the formation of aromatic organozinc reagents and their coupling with 2-chlorodia
Electrochemical cross-coupling between functionalized aryl halides and 2-chloropyrimidine or 2-chloropyrazine catalyzed by nickel 2,2'-bipyridine complex
Gosmini, Corinne,Nédélec, Jean Yves,Périchon, Jacques
, p. 201 - 203 (2007/10/03)
2-Arylpyrimidines and 2-arylpyrazines have been obtained in good to high yields from 2-chloropyrimidine and 2-chloropyrazine and various functionalized aryl halides by electroreduction using an iron rod as the anode and a catalytic amount of nickel-bipyridine complex in a mixture of DMF and pyridine as solvent.
