英文摘要: The direct iodination of polyfluorinated vinyl stannanes by tin-iodine exchange methodology was achieved giving (Z)-alpha-fluoro-beta-trifluoromethyl vinyl iodides stereospecifically. Changing the substituent in R group from the electron-withdrawing group to electron-donating group led to an increase in the yield from 78 % to 90 %, while it was moved from para to meta position the reaction did not afford a dramatic change in the yield (90 % to 95 %). In addition, this reaction also can be applied to the vinyl stannane with heterocyclic group. The further coupling reaction of prepared vinyl iodide containing heterocyclic moiety with (Z)-alpha-fluoro-beta-trifluoromethylstannanes gave polyfluorinated heterocyclic alkadienes with 2E,4E-selectivity.
