摘要

The 13C NMR spectra of conformationally rigid arylcylopropanes have been examined in order to determine the strength and conformational dependence of the benzene- cyclopropane interaction. Previous work with conformationally flexible arylcyclopropanes has implicated both conjugative and hyperconjugative interactions between the aromatic r- system and the bonding orbitals of cyclopropane. The substituent-induced chemical shifts ...
