(Matrix presented) The stereocontrolled dehydrobromination of 1,2-dibromoethyl carboxylates giving (Z)-2-bromovinyl carboxylates could readily be approached by using DBU and a catalytic amount of hydroquinone as a base at -78°C. The first investigation on

Treatment of (Z)-(β-benzoyloxyvinyl)phenyl-λ3- iodanes, readily prepared from ethynyl(phenyl)(tetrafluoroborato)- λ3-iodane via stereoselective Michael-type addition of benzoic acids in methanol in the presence of sodium benzoates, with tetrabutylammonium halides in THF at 65°C results in a vinylic SN2 reaction to give the inverted (E)-β-benzoyloxyvinyl halides in high yields.
