Abstract
The mechanism of thermal decomposition of nine acetylenic esters has been examined under conditions of flash vacuum pyrolysis. The products formed may be explained by a series of well-precedented steps involving such processes as ene reactions, alkyne to vinylidene rearrangements, carbene CH insertions, and fragmentation of 2,3-dihydrofuran-2-ones or 5,6-dihydropyran-2-ones with extrusion of CO and CO2 respectively.
