Electrochemical Intramolecular C-H Amination: Synthesis of Benzoxazoles and Benzothiazoles was written by Morofuji, Tatsuya;Shimizu, Akihiro;Yoshida, Jun-ichi. And the article was included in Chemistry – A European Journal in 2015.COA of Formula: C11H9NO This article mentions the following:
A new method for metal-free intramol. C-H amination has been developed. Electrochem. oxidation of 2-pyrimidyloxybenzenes and 2-pyrimidylthiobenzenes, which can be easily prepared from phenols and thiophenols, resp., followed by the treatment of the resulting pyrimidinium ions with piperidine gives 2-aminobenzoxazoles and 2-aminobenzothiazoles, resp. In the experiment, the researchers used many compounds, for example, 2-Phenoxypyridine (cas: 4783-68-0COA of Formula: C11H9NO).
2-Phenoxypyridine (cas: 4783-68-0) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. 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.COA of Formula: C11H9NO
