Etude des conditions d'acces au tetrazolo-1,2,3,4-triazino-1,2,4-indazole et au thioxo-3 triazolo-1,2,4-triazino-1,2,4-indazole

The triazinoindazolones 8 and 9 were synthesized by rearrangement of the oxadiazoles 5 and 6 or by cyclising the indazolic ethoxymethylidenehydrazides 2 and 3.The triazinoindazolethiones 17 and 18 which were obtained by thionation of the triazinoindazolones 8 and 9 constitute the intermediates to the hydrazinoindazoles 19 and 20.The tetrazolotriazinoindazole 21 was obtained by cyclising the hydrazoindazole 19.The potassium indazolyldithiocarbazate 12 has been used for the synthesis of 4-thioxotriazinoindazolone 10 and 4-amino-3-thioxotriazolylindazole 15.The cyclisation of the latter gave the 3-thioxotriazinoindazolone 16.The structure of the derivatives was confirmed by 1H-nmr.
