Abstract:

The synthesis of novel functionalized 3,6-di(2-pyridyl)pyridazines via an inverse electron demand Diels−Alder reaction between the corresponding 3,6-di(2-pyridyl)-1,2,4,5-tetrazine and various alkynes is reported. The resulting 3,6-di(2- pyridyl)pyridazines were investigated using X-ray crystallography, IR spectroscopy, and NMR spectroscopy, whereby several 2D NMR spectroscopic techniques were exploited to conclusively assign all proton- and carbon-resonances. In addition, it was demonstrated that the functionalized 3,6-di(2- pyridyl)pyridazines are capable of forming [2 × 2] grid-like metal complexes with copper(I) and silver(I) ions.
