Abstract
The alkylation of 2,3-dichloropyrazine with the Meerwein reagents R3O+BF4- (R = Me or Et) afforded 1-alkyl-2,3-dichloropyrazinium tetrafluoroborates, which were transformed into mono- or disubstitution products, while the rea ction of these salts with 1,4-N,X-dinucleophiles resulted in fused heterocy clic systems.
