Article abstract of DOI:10.1002/jhet.5570370434

The reaction of 3-chloro-6-phenyl-1,2,4-triazine 1a with carbon nucleophiles 2a-d bearing a cyano substituent at a carbanionic center has been studied. In all reactions the formation of the corresponding 3-aminopyridazines 3a-d takes place via ANRORC mech
