• 31P NMR experiments revealed rapid decomposition of the Ph3PAu+TfO− complex in the presence of the furan-yne, which resulted in poor reactivity as reported in the literature. Therefore, instead of tuning different ligands (PR3), the 1,2,3-triazole was applied as a special X-factor to stabilize the catalyst. The desired phenol products were prepared in excellent yields (1% cat. up to 95% yield) and chemoselectivity (>20:1).
