Abstract

A route to 3,6-dihydrazinopyridazine from dithiomaleohydrazide is confirmed and improved and the product now characterised. Possible alternative routes,e.g, from 3,6-dichloro-, -diphenoxy-, and -dimethylthio-pyridazine, yielded the monohydrazino-compounds, whilst 3,6-di-p-tolylsulphonyloxypyridazine with hydrazine afforded maleodihydrazide. A previously described method from 3,6-dimethoxypyridazine and hydrazine is shown to yield a mixture of oxygen-containing products, deduced as comprising 6-hydrazino-5-amino-2,3-dihydro-3-oxopyrid-azine together with some of the 6-methoxy-analogue.
