Reference of 2-Ethylbenzo[d]oxazole. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2-Ethylbenzo[d]oxazole, is researched, Molecular C9H9NO, CAS is 6797-13-3, about ZrOCl2.8H2O as an efficient, environmentally friendly and reusable catalyst for synthesis of benzoxazoles, benzothiazoles, benzimidazoles and oxazolo[4,5-b]pyridines under solvent-free conditions. Author is Mohammadpoor-Baltork, Iraj; Khosropour, Ahmad Reza; Hojati, Seyedeh Fatemeh.
A new and efficient method for the preparation of benzoxazoles, benzothiazoles, benzimidazoles, and oxazolo[4,5-b]pyridines from reactions of orthoesters with o-substituted aminoaroms. and 2-amino-3-hydroxypyridine in the presence of catalytic amounts of the moisture stable, inexpensive ZrOCl2.8H2O under solvent-free conditions was presented. This new protocol had the advantages of easy availability, easy handling, stability, reusability and eco-friendly of the catalyst, high yields, very short reaction times, solvent-free reaction conditions, simple exptl. and work-up procedure.
Different reactions of this compound(2-Ethylbenzo[d]oxazole)Reference of 2-Ethylbenzo[d]oxazole require different conditions, so the reaction conditions are very important.
