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/CHactivation process. This reaction can also be expanded to non-fluorinated substrates.

Treatment of various types of N-(o-haloaryl)-alkynylimines in the presence of Pd(PPh3)2Cl2 gave 2-trifluoromethylindoles in high yields. This approach provides a novel and facile access to the biologically important fluorine-containing indole derivatives.
