Homogeneous Gold Catalysis: Development and Recent Advances
Tapas Adak
Abstract
Gold catalysis has witnessed remarkable advances over the past decade, with numerous insightful reviews chronicling this progress. However, a comprehensive review addressing developments in the field during the post-pandemic COVID era remains notably absent. This review aims to bridge that gap by providing an in-depth analysis of recent studies, shedding light on the unique properties of gold complexes, particularly the intriguing aurophilic interactions that distinguish gold chemistry. The review systematically explores the latest achievements in both mono- and dinuclear gold-catalyzed reactions, with a focus on their applications in diverse fields, including redox coupling, asymmetric catalysis, photo-, and electrocatalysis. A special emphasis is placed on the comparative performance of mono- and dinuclear gold catalysts, with the latter often exhibiting enhanced catalytic efficiency and selectivity in certain reactions. By integrating mechanistic insights and DFT perspectives with representative experimental studies from recent years, this review highlights the significance of gold catalysis to synthetic chemistry, identifies emerging trends and outlines future directions for the field.
