The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine, is researched, Molecular C8H7BrO2, CAS is 52287-51-1, about Palladium-catalyzed cyanation of aryl halides with in situ generated CN- from ClCF2H and NaNH2, the main research direction is aryl nitrile preparation palladium catalyst in situ cyanide anion; chlorodifluoromethane sodium amide aryl halide cyanation.Computed Properties of C8H7BrO2.
An efficient Pd-catalyzed cyanation of aryl halides with in situ generated CN- anions is described. The CN- source stems from the quadruple cleavage of chlorodifluoromethane (ClCF2H) with sodium amide (NaNH2). This transformation features no requirement of a toxic CN source and avoids the problem of HCN generation associated with traditional methods. A series of aryl nitriles are obtained from aryl halides in good yields under mild reaction conditions.
