The structure analysis explains that the gold‐catalyzed reaction forms one benzene ring possessing an acetoxyethenyl and an acetoxy groups in 2 and 4 positions. Based on the X‐ray analysis, we revised structures of all products reported previously in two papers. The proposed mechanism of this sequence is being revised with an evidence of gold‐carbene intermediacy. The proposed gold‐carbene intermediate was supported by the control experiment for enyne metathesis route.
