Palladium-Catalyzed Synthesis of 2-Fluoroalkyl-3-methylene-3H-indoles Through a Domino Carbopalladation/CH Activation Process

A novel palladium‐catalyzed synthesis of substituted 3‐methylene‐3H‐indoles from readily accessible alkynylimines has been developed. A wide variety of 2‐fluoroalkyl‐3‐methylene‐3H‐indoles were synthesized in moderate to good yields through this cascade carbopalladation/CH activation process. This...

Zusammenfassung:	A novel palladium‐catalyzed synthesis of substituted 3‐methylene‐3H‐indoles from readily accessible alkynylimines has been developed. A wide variety of 2‐fluoroalkyl‐3‐methylene‐3H‐indoles were synthesized in moderate to good yields through this cascade carbopalladation/CH activation process. This reaction can also be expanded to non‐fluorinated substrates.
