The Uses of 4-Methylpyridazine
4-Methylpyridazine was used in the preparation of series of novel pyridazine derivatives structurally related to bipyridine cardiotonics.
Reactions
4-methylpyridazine could be used as a starting material to synthesize a series of novel pyridazine derivatives structurally related to bipyridine cardiotonics[1].
Pyridazine (pydz) and 4-methylpyridazine (4Me-pydz) could form stable bis(monodentate) complexes of general formulae fac-[PtXMe3L2](X = Cl, Br or I) and fac-[ReX(CO)3L2](X = Cl, Br or I). These complexes in above-ambient temperature solutions exhibit 1,2-fluxional shifts between the nitrogen donor pairs of each ring[2].
General Description
Products of reaction of methyl iodide with 4-methylpyridazine has been investigated by NMR spectra. Solvent free oxidation of 4-methylpyridazine by acetyl peroxyborate, peracetic acid and hydrogen peroxide has been reported.
