Abstract: We have synthesized 5-acylbicyclo[2.2.1]hept-2-enes by diene addition and ethynylated with lithium aluminium acetylide. We have studied the ratio of endo- and exo-isomers in dependence on their preparation temperature and polarity of solvents as well as the kinetics of isomerization and the equilibrium of the endo- and ежо-isomer mixture. We have calculated the rate constant of isomerization when sodium ethoxide was used as catalyst.
