The referees suggested that the HCl produced from the gold catalyst could be responsible for the observed etherification reaction. To assure that this possibility can be ruled out, several control experiments were performed. In general, much less efficient transformations were achieved when reactions were catalysed by 5% HCl. For instance, the reaction of 1 a with 2 f gave a mixture of unsymmetrical ether (35% yield; 72% under gold(III) catalysis) and symmetrical ether (14% yield, On the other hand, indanol 1b and isopropanol (2f) gave a mixture of unsymmetrical ether (45, and indene (28, elimination product, No reaction took place between tertiary alcohol 2 g and isopropanol (2f) with 5% HCl
