Photochemical behavior of some nitrogen heterocyclics

The compounds, 3,6-dimethoxypyridazine, l,2-dimethyl- 3,6(1H,2H)-pyridazinedione, and 6-methoxy-2-methyl-3(2H)­ pyridazinone, were prepared by using reported preparations. Their photochemistry was investigated and compared to the thermal chemistry and photochemistry of maleic hydrazide
