Abstract
Thermal Rearrangements, XVII1). – Gas Phase Pyrolysis of CyclopropylacetyleneThe gas phase pyrolysis of cyclopropylacetylene (3) has been investigated in a flow system between 600 and 900°C. At the lower temperature limit 3 isomerizes to give 1,2,4‐pentatriene (9), cis‐ (10) and trans‐3‐penten‐1‐yne (11), as well as 1‐penten 4‐yne (12), all isomers being formed in roughly equal amounts. At 850°C none of these C5H6‐hydrocarbons is formed; rather, 1,3‐cyclopentadiene (13), benzene (14), toluene (15), indene (16), naphthalene (17), and acenaphthylene (18) are the major constituents of a complex pyrolysate. The mechanisms of formation of the major pyrolysis products are discussed.Keywords
