Palladium-catalyzed direct carboxylation of aryl bromides with carbon dioxide.

J. Am. Chem. Soc. 131 , 15974, (2009)

A novel protocol for the direct carbon dioxide insertion (CO(2)) into aryl halides in a catalytic manner is presented herein. Unlike other carboxylation methods using CO(2), there is no need for the s...

The selective reaction of aryl halides with KOH: synthesis of phenols, aromatic ethers, and benzofurans.

J. Am. Chem. Soc. 128 , 10694, (2006)

The direct and selective synthesis of phenols from aryl/heteroaryl halides and KOH has been achieved through the use of highly active monophosphine-based catalysts derived from Pd(2)dba(3) and ligands...
