The kinetics of pyrolysis of 1,3,3-trimethylcyclopropene. Evidence for the involvement of alkylidene carbenes in the thermal isomerisation of cyclopropenes
Abstract
A low yield of 4-methylpent-2-yne in the gas-phase isomerisation of 1,3,3-trimethylcyclopropene is shown to be more consistent with an alkylidene carbene transient than with a, 1,3-biradical intermediate.
