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