摘要

(trans) 1-Chloro-2-iodoethylene (),(trans) 1-bromo-2-iodoethylene (),(trans) 1, 2- diiodoethylene () and (cis and trans) 1, 2-dibromoethylene () were reacted under Suzuki, Sonogashira and Negishi cross-coupling conditions using Pd catalysis to obtain mono coupled products. Only olefin template provided the desired coupling products reliably under all reaction conditions. Compound did not provide cross coupled products under ...
