Vibrational spectra of pyridazine, pyridazine-d4, pyridazine-3,6-d2 and pyridazine-4,5-d2

Spectrochimica Acta Part A: Molecular Spectroscopy, 1967
Abstract Infrared spectra of the liquids pyridazine, pyridazine- d 4 and pyridazine-3,6- d 2 are reported from 270 to 4,000 cm −1 . Raman spectra are reported for these liquids with the state of polarization for many lines. The vibrational assignment suggested for these three compounds satisfies the three Teller—Redlich product rules within ...

SYNTHESIS OF NEW PYRIDAZIN- 6-ONES, PYRIDAZIN-6-IMINES, 4-PYRIDAZINALS, AND PYRIDINES

Synthetic Communications, 2002
ABSTRACT 3-Dimethyl-1-[3-methyl-(4H)-5-phenylimidazol[2,1-b]thiazol-2-yl]prop-2-enone 4 couples smoothly with benzenediazonium chloride to yield propanal 5 which is a key intermediate for the synthesis of pyridazinones 9–13, 16 and pyridazine-6-imine 8, 19.

Pyridazines. III. The synthesis of substituted pyridazines

Journal of Heterocyclic Chemistry, 1965
AbstractA series of pyridazines and pyridazones have been prepared substituted with alkyl, alkoxyl, halogen, mercapto, substituted mercapto, phenyl, morpholino, piperidino, styryl, substituted styryl and pyridylethenyl groups as potential antitumor agents. The compounds possessing antitumor or tissue culture activity are recorded in Table VI.

Pyridazines. LXXXIV. Studies on borohydride reduction of pyridazine compounds

Journal of Heterocyclic Chemistry, 1976
AbstractImidazo[1,2‐b]pyridazine, s‐triazolo[4,3‐b]pyridazine and tetrazolo[1,5‐b]pyridazine and some derivatives thereof were reduced with sodium borohydride to give the corresponding 5,6,7,8‐tetrahydro derivatives. A mechanism for these reductions is proposed and reduction at the C7‐C8 bond occurs before the reduction of the C6N5 bond.
