We report herein the copper- and palladium-catalyzed decarboxylative cross-coupling reactions of alkynyl carboxylic acids and N-tosylhydrazones, affording trisubstituted allenes and conjugated enynes, respectively. With readily available alkynyl carboxylic acids as the acetylene surrogates, the new strategies are operationally simple and show good functional group tolerance.
