ortho-Substituted aryl silanes have previously been found to undergo much slower Au-catalyzed intermolecular arylation than their m,p-substituted isomers, with many examples failing to undergo turnover at all. A method to indirectly quantify the rates of C–Si auration of o-substituted aryl silanes, under conditions of turnover, has been developed. All examples are found to undergo very efficient C–Si
