Rh(I)-catalyzed coupling cyclization of N-aryl trifluoroacetimidoyl chlorides with alkynes: one-pot synthesis of fluorinated quinolines.
[reaction: see text]. Rh(I) complexes were found to catalyze the coupling cyclization of N-aryl trifluoroacetimidoyl chlorides with alkynes to afford 2-trifluoromethylated quinolines in good yields. Various alkynes were applied to this cyclization coupling with regioselectivity.
