Alcoholysis of Binor-S with Alcohols under the Action of Ionic Liquid
- 18 Downloads
Inorganic ionic liquids are first shown to catalyze the alcoholysis of heptacyclo-[8.4.0.02,12.03,8.04,6.05,9.011,13]tetradecane (heptacyclic dimer of norbornadiene, binor-S) with primary and secondary alcohols. The reaction occurs at 65−100°C for 6−14 h via regioselective cleavage of the cyclopropane C4−C5 bond in binor-S to form 10-exo-alkoxyhexacyclo[9.2.1.02,7.03,5.04,8.09,13] tetradecanes in 85−90% yields.
