Abstract In this minireview we survey the challenges and strategies in gold redox catalysis. Gold's reluctance to oxidative addition reactions due its high potential limits applicability. Initial attempts overcome problem focused on use of sacrificial external oxidants stoichiometric amounts bring Au(I) compounds Au(III) reactive species. Recently, innovative approaches employing hemilabile ligands, which are capable coordinating stabilizing square‐planar intermediates, thus facilitating...
Abstract Oxidant‐free Au(I)/Au(III) catalysis can still be regarded as a young and promising chemistry. Because the first examples of gold were limited to activation functionalization π‐C−C bonds very little was known on fundamental organometallic transformations at gold, countless works during past 15 years have been devoted disclosing elementary reactivity implementing it in catalysis. Remarkably, great emphasis triggering oxidative addition Au(I) has placed, high redox potential pair...
A novel hemilabile MIC^N ligand-based Au( i )-catalytic procedure for the synthesis of γ-substituted γ-butyrolactones through arylation-lactonization reaction corresponding γ-alkenoic acid is presented.
Gold(<sc>iii</sc>) complexes are garnering increasing interest for opto-electronic, therapeutic and catalytic applications.

The Lewis-acidic character and robustness of NHC-Au(I) complexes enable them to catalyze a large number reactions, they are enthroned as the catalysts choice for many transformations among polyunsaturated substrates. More recently, Au(I)/Au(III) catalysis has been explored either by utilizing external oxidants or seeking oxidative addition processes with featuring pendant coordinating groups. Herein, we describe synthesis characterization N-heterocyclic carbene (NHC)-based Au(I) complexes,...
