Palladium‐Catalyzed Direct Denitrogenative C‐3‐Arylation of 1
A novel palladium‐catalyzed approach to direct C‐3‐arylation of 1H‐indoles with arylhydrazines using air as the oxidant via CN bond cleavage has been developed. Various substituents are tolerated in this system in moderate to good yields. This reaction could also be compatible with a larger scale. Thus, this strategy using arylhydrazines as arylating reagents provides a powerful method for constructing substituted 3‐aryl‐1H‐indoles.
