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
通过相应的 3,6-二(2-吡啶基)-1,2,4,5-四嗪和各种不同的电子需求 Diels-Alder 反应合成新型官能化 3,6-二(2-吡啶基)哒嗪报道了炔烃。使用 X 射线晶体学、红外光谱和核磁共振光谱研究了所得的 3,6-二 (2-吡啶基) 哒嗪,其中利用了几种 2D 核磁共振光谱技术来最终分配所有质子和碳共振。此外,已证明功能化的 3,6-二(2-吡啶基)哒嗪能够与铜 (I) 和银 (I) 离子形成 [2 × 2] 网格状金属络合物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
