Thermic reaction of thiopyridones was written by Krowicki, Krzysztof. And the article was included in Polish Journal of Chemistry in 1978.Formula: C11H9NO This article mentions the following:
4-Pyridinethione (I) was heated in refluxing decalin containing heptanal to give 90% R2S (R = 4-pyridinyl). I was heated with 3-pyridinethiol, PhSH, and PhOH to give 3,4′-dipyridyl sulfide, RSPh, and ROPh; resp. 2-Pyridinethione underwent analogous transformations. In the experiment, the researchers used many compounds, for example, 2-Phenoxypyridine (cas: 4783-68-0Formula: C11H9NO).
2-Phenoxypyridine (cas: 4783-68-0) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Formula: C11H9NO
