Safety of 6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine, is researched, Molecular C8H7BrO2, CAS is 52287-51-1, about Mechanism of Ar1-5 and Ar2-6 cyclization of 2-phenoxyethanols. Author is Goosen, Andre; McCleland, Cedric W..
In the photoreaction of para-substituted 2-phenoxyethanols with HgO and iodine, Ar1-5 cyclization is a reversible process, and the Ar2-6 product is formed by direct ortho alkoxylation, not via rearrangement of an Ar1-5 intermediate. 3-Arylpropan-1-ols, when reacted under the same conditions, afford mainly the Ar2-6 product by a sigmatropic 1,2-rearrangement of the intermediate Ar1-5 carbocation.
《Mechanism of Ar1-5 and Ar2-6 cyclization of 2-phenoxyethanols》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine)Safety of 6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine.
