摘要：

A variety of arylalkynoic acids reacted with 1,3-diiodo-5,5-dimethylhydantoin and HF.pyridine in the presence of AgOAc to provide the corresponding 1-fluoro-2,2-diiodovinylarenes in good yields and high regioselectivity. In addition, Pd-catalyzed cross-coupling reaction of 1-fluoro-2,2-diiodovinylarenes afforded diaryl coupling products in the Suzuki reaction and monoaryl coupling products with high stereo-selectivity in the Hiyama reaction. It was found that C-F-activated borylation of fluoroalkenes using Pd catalyst afforded the vinylboranes with good yields.
