Abstract

Abstract: A triflamide‐tethered N‐heterocyclic carbene (NHC)‐bound Rh I dicarbonyl catalyst was highly effective for both intermolecular hydroalkoxylation and intramolecular heteroannulation reactions. The involvement of both the amido nitrogen and triflato oxygen atoms of the triflamide functionality for alcohol activation and 1, 2‐hydrogen shift, respectively, was proposed.

The involvement of both the amido nitrogen atom and the triflato oxygen atom of the triflamide functionality for alcohol activation and 1, 2‐hydrogen shift, respectively, is proposed.
