摘要

Cu (II)-catalyzed coupling of polymer-bound ω-haloalkyn-l-ols to terminal alkynes proceeds in moderate yield to give unsymmetrical diynes upon hydrolytic removal from the polymer. Formation of the symmetrical homocoupled byproduct is suppressed relative to conventional Cadiot-Chodkiewicz conditions in homogeneous solution.
