title: Redox-neutral atom-economic rhodium-catalyzed coupling of terminal alkynes with carboxylic acids toward branched allylic esters.
abstract: A new method for the preparation of a wide range of branched allylic esters from terminal alkynes that proceeds via a redox-neutral propargylic CH activation employing a rhodium(I)/DPEphos catalyst is reported.
