Synthesis of α,β-unsaturated aryl esters via Heck reaction of unsymmetrical aryl tellurides
摘要:
A variety of alpha,beta-unsaturated aryl esters were prepared by the direct reaction of unsymmetrical aryltellurides and ethyl acrylate, catalyzed by PdCl2 via a Heck cross-coupling reaction. (C) 2009 Elsevier Ltd. All rights reserved.
arylboronic acids by usingcopper(I) thiophene-2-carboxylate (CuTC) under mild conditions. Although other studies have reported that highly polar solvents (such as DMSO) or bases are required, this reaction was completed by using CuTC and common solvents under neutral conditions at room temperature. This cross-coupling reaction was performed with diaryl ditellurides and arylboronic acids bearing various
