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.

A visible-lightinduced intramolecular radicalcyclization of N-[2-(alkynyl)phenyl]trifluoroacetimidoyl chlorides is described. The reaction allows the rapid construction of diverse 2-trifluoromethyl-3-acylindoles in a sequential C–C and C–O bond formation process under mild conditions.
