Copper(I)-catalyzed cycloaddition of substituted cyclohexenyl acetylenes with azido(per)fluoroalkanes afforded 4-cyclohexenyl-substituted N-(per)fluoroalkylated 1,2,3-triazoles. Their rhodium(II)-catalyzed transannulation led to fused N-(per)fluoroalkyl pyrroles and subsequent oxidation provided N-(per)fluoroalkyl indoles.
