efficient and novel method to prepare branched 1,3-enynes via Pd(II)-catalyzed decarboxylative coupling of arylalkynyl carboxylicacids with allylic ethers under mild conditions. Various arylalkynyl carboxylicacids and allylic ethers could participate in the reaction, regioselectively affording the desired branched 1,3-enynes in moderate to good yields.
