Palladium-catalyzed salt-free double decarboxylative aryl allylation?

Organic & Biomolecular Chemistry Pub Date: 2018-08-15 DOI: 10.1039/C8OB01806E

Abstract

This report describes a palladium-catalyzed decarboxylative aryl allylation between unactivated benzoic acids and allylic carbonates. This transformation successfully couples a variety of carbonates and benzoic acids in good yield (up to 94%) using 1 mol% palladium. This salt free allyl-arylation proceeds without added base, copper, or silver. The only stoichiometric byproducts are carbon dioxide and tert-butanol.
