Recent advances in direct C-H arylation: Methodology, selectivity and mechanism in oxazole series

Abstract

Catalytic direct (hetero)arylation of (hetero)arenes is an attractive alternative to traditional Kumada, Stille, Negishi and Suzuki-Miyaura cross-coupling reactions, notably as it avoids the prior preparation and isolation of (hetero)arylmetals. Developments of this methodology in the oxazole series are reviewed in this article. Methodologies, selectivity, mechanism and future aspects are presented. © 2011 Verrier et al; licensee Beilstein-Institut.
