[1]Benzothieno[2,3-d]pyridazines V. Etude des Réactions de substitution des Benzothiéno[2,3-d]pyridazinethiones

The substitution and addition reactions of the 2H1]benzothiéno2,3-d]phyridazinethione-1 and the 3H1]benzothiéno2,3-d]pyridazinethione-4 gave N- or S-substituted derivatives whose structures were identified by 1R and NMR spectroscopy.
