- Abstract
- 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.
