Heterocyclic synthesis with nitriles: synthesis of pyridazine and pyridopyridazine derivatives [PDF]

open access: yes, 2007
The reaction of MND with aryldiazonium chlorides followed by cyclization afforded the pyridazinimine derivatives. Reaction of the latter with another mole of malononitrile produce only pyrido[3,2-c]pyridazine derivatives.

Bis(dicyanamido-κN)tetrakis(pyridazine-κN)nickel(II)

open access: yesActa Crystallographica Section E, 2012
Reaction of nickel(II) chloride with sodium dicyanamide and pyridazine leads to single crystals of the title compound, [Ni{N(CN)2}2(C4H4N2)4], in which the NiII cation is octahedrally coordinated by two dicyanamide anions and four pyridazine ligands into

Immobilization of Fe(III) complexes of pyridazine derivatives prepared from biosorbents supported on zeolites [PDF]

open access: yes, 2008
Immobilization of Fe(III) complexes of pyridazine derivatives was achieved in NaY zeolite, loaded with iron through the action of a robust biosorption mediator consisting of a bacterial biofilm, Arthrobacter viscosus, supported on the zeolite.

Tandem mass spectrometric study of annelation isomers of the novel thieno[3',2':4,5]pyrido[2,3-d]pyridazine ring system [PDF]

open access: yes, 2014
In the present communication, we describe tandem combinations of Suzuki - condensation ring closure reactions to obtain a novel thieno[3 -,2 -:4,5]pyrido[2,3-d]pyridazine ring system. These compounds were studied by tandem mass spectrometry in detail and
