A new sequential, tandem synthesis of functionalized α-arylnitriles via the bromination/cyanation/deformylation of substituted deoxybenzoin has developed. CuBr2-promoted bromination of substituted deoxybenzoins gives 2-bromo-2-arylacetophenne 3. The cyanation of 3 with sodium cyanide (NaCN) generates epoxynitrile. Then, a treatment of epoxynitrile with BF3·OEt2 results in the formation of functionalized α-arylnitriles 4 via a 1,2-aryl shift.
