2-Iodoaniline reacts with terminal acetylenic carbinols in THF at 80 degrees C in the presence of a catalytic amount of PdCl2(PPh3)(2) and CuI along with aqueous tetrabutylammonium hydroxide to afford the corresponding 2-arylquinolines in good yields. The catalytic pathway seems to be proceeded via a sequence involving initial Sonogashira coupling between 2-iodoaniline and terminal acetylenic carbinols to form coupled acetylenic carbinols, isomerization of coupled acetylenic carbinols to alpha,beta-unsaturated ketones, and cyclodehydration.
