N,N-coupled heterobicycles from cyclic hydrazine derivatives. Part 8: Synthesis of 3-imino substituted 1-thioxo-2,3,5,10-tetrahydro-[1,2,4]triazolo[1,2-b]phthalazines and 1-thioxo-5,10-dihydro-[1,3,4]thiadiazolo[3,4-b]phthalazines

The preparation of the mostly 3-arylimino substituted derivatives 4 of the hitherto unknown [1,3,4]thiadiazolo[3,4-b]phthalazine ring system succeeded by treatment of the related 2-thiocarbamoyl-1,2,3,4-tetrahydrophthalazines 2 with thiophosgene under mild conditions. The reaction of the 2 with arylisothiocyanates under heating yields the 2-aryl-1-thioxo-3-arylimino[1,2,4]triazolo[1,2-b]phthalazines 5.
