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.mono- or disubstitution products, while the reaction of these salts with 1,4-N,Xdinucleophiles resulted in fused heterocyclic systems.
