Abstract

Reaction of bis (collidine) iodine (I)(or bromine (I)) hexafluorophosphate with acetylenic acids led to the corresponding iodo (or bromo) acetylenes in high yields. This halodecarboxylation reaction was also observed with acrylic acids substituted in position 3 by an aryl group or an heteroatom.
