Synthesis And Structure Of A Substituted Pyridazine, Kiranmai Byrichetti

Masters Theses & Specialist Projects

Pyridazines are heterocyclic compounds with an N-N bond in their ring structure. Heterocyclic aromatic compounds are of great interest as a result of their novel properties and commercial applications. Our current research is focused on the potential role of pyridazines in next generation electronic devices that utilize organics as the semiconducting material. The synthesis of 5, 6-fused ring pyridazines beginning from fulvenes (Scheme 1) is described herein. These fused heterocycles will serve as synthetic models and building blocks for potential organic or organometallic conducting polymers.

Our goal was to modify the route of Snyder et al. previously reported for the …

Heterocyclic organic and organometallic compounds (e.g. polypyrrole, Figure 1A) and their derivatives have been of great interest for conductive polymers due to their novel properties, such as their versatile structure and ease of synthesis. In addition, these molecules have a great environmental stability compared to non-aromatic analogs (e.g. polyacetylene, Figure 1B). We have been interested in synthesizing organometallic pyridazyl (Figure 1C) complexes for polymer research. Figure 1. Structures of A–D. Pyridazyl complexes of rhenium were synthesized in three steps beginning from 1,2-diacylcyclopentadienes (aka, fulvenes, Figure 1D).
