Palladium-catalyzed directing group-assisted C8-triflation of naphthalenes

Chem Commun (Camb). 2016 May 10;52(40):6709-11. doi: 10.1039/c6cc01732k.

Abstract

The transition-metal-catalyzed direct triflation of naphthyl amides and naphthyl ketones has been accomplished for the first time. Benzophenone (BP) was found to be a suitable ligand for the cross-coupling reactions. Density functional theory (DFT) calculations revealed that excessive amounts of HOTf inhibit the reductive elimination of the C-F bond to realize the unusual reductive elimination of the C-OTf bond.
