Benzoxazole or Benzothiazole as an Innate Directing Group for Palladium- and Ruthenium-Catalyzed Complementary C–H Arylation: Functionalization of Biorelevant Heterocyclic Scaffolds.

The article discusses the use of benzoxazole and benzothiazole as directing groups for palladium- and ruthenium-catalyzed C-H arylation reactions. The authors explore different reaction conditions and catalysts to achieve selective arylation of these compounds. They also investigate the effects of substituents on the aryl unit and the benzoxazole/benzothiazole moiety. The document provides valuable information for researchers interested in the synthesis and functionalization of heterocyclic compounds. Additionally, the document includes experimental procedures and characterization data for specific compounds synthesized using the methods discussed. [Extracted from the article]
