摘要：
Examples of palladium-catalyzed reactions of 2-alkynyl esters via the 2-alkynylpalladium intermediates are presented. The palladium-catalyzed hydrogenolysis of 2-alkynyl formates, which have internal triple bonds, affords alkynes via the 2-alkynylpalladium as an intermediate. The elimination reaction of 2-alkynyl carbonates yields conjugated enynes via the 2-alkynylpalladium intermediates.
