摘要：

NHC-Pd-PEPPSI complexes with bulky benzyladamantyl substituted N-heterocyclic carbenes (NHC) were synthesized and characterized by NMR, HRMS, and micro analysis. These complexes were then used for Suzuki-Miyaura coupling reactions between aryl bromides and phenylboronic acid. With low catalyst, loading, all synthesized complexes rapidly catalyzed the Suzuki-Miyaura cross-coupling reaction in iPrOH/water (1:3 v/v) at room temperature in air. All palladium compounds were stable and had high catalytic activity for the Suzuki-Miyaura coupling reaction. (C) 2017 Elsevier Ltd. All rights reserved.
