Abstract

A (N,CAr,CAlk) Au(iii) pincer complex has been synthesized from Au(OAc)3 (OAc = OCOCH3) and 2-(3,5-di-tert-butylphenyl)pyridine (L1) involving a Csp3-H bond activation by electrophilic substitution. In agreement with DFT calculations, the resulting complex significantly improves the performance of Au(tpy)(OAcF)2 (tpy = 2-(p-tolyl)pyridine, OAcF = OCOCF3) in the catalytic trifluoroacetylation of acetylene.

摘要

已通过 Au(OAc)3(OAc = OCOCH3)和 2-(3,5-二叔丁基苯基)吡啶(L1)之间的 Csp3-H 键活化的亲电取代反应合成了(N,CAr,CAlk)Au(iii) 夹式配合物。与 DFT 计算结果一致,所得配合物显著提高了 Au(tpy)(OAcF)2(tpy = 2-(对甲苯基)吡啶,OAcF = OCOCF3)在乙炔三氟乙酰化反应中的催化性能。
