A novel and selective protocol for the synthesis of 1-allyl-2-ethynylbenzenes has been developed by palladium-catalyzed decarboxylative coupling of allylic alkynoates with arynes. This new route allows for both sp−sp2 and sp2−sp3 couplings of allylic alkynoates with arynes in one pot involving a decarboxylation process.
