Br?nsted acid-catalyzed chlorination of aromatic carboxylic acids

The chlorination of aromatic carboxylic acids with SOCl2 has been effectively performed by reacting with a Br?nsted acid as the catalyst. Based on this discovery, an efficient catalytic method that is cheaper than traditional catalytic methods was developed. 20 substrates were chlorinated offering excellent yields in a short reaction time. And the SOCl2/Br?nsted acid system has been used in a larger scale preparative reaction. A dual activation mechanism was proposed to prove the irreplaceable system of SOCl2/Br?nsted acid.

Copper-catalyzed remote C–H arylation of polycyclic aromatic hydrocarbons (PAHs)

The regioselective C–H arylation of substituted polycyclic aromatic hydrocarbons (PAHs) is a desired but challenging task. A copper-catalyzed C7–H arylation of 1-naphthamides has been developed by using aryliodonium salts as arylating reagents. This protocol does not need to use precious metal catalysts and tolerates wide variety of functional groups. Under standard conditions, the remote C–H arylation of other PAHs including phenanthrene-9-carboxamide, pyrene-1-carboxamide and fluoranthene-3carboxamide has also accomplished, which provides an opportunity for the development of diverse organic optoelectronic materials.

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

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.
