Alcoholysis of Binor-S with Alcohols under the Action of Ionic Liquid

Аннотация

Inorganic ionic liquids are first shown to catalyze the alcoholysis of heptacyclo-[8.4.0.0^2,12.0^3,8.0^4,6.0^5,9.0^11,13]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[9.2.1.0^2,7.0^3,5.0^4,8.0^9,13] tetradecanes in 85−90% yields.
