NUCLEAR MAGNETIC RESONANCE SPECTROCOPY. CYCLO PROPANE DERIVATES

Abstract

Chemical shifts and coupling constants have been determined from the analysis of proton nuclear magnetic resonance spectra for a series of cyclo propane derivatives. The geminal and vicinal cyclopropyl couplings have opposite signs. Additional 13C-H coupling constants have been obtained for cyclopropanes which support the conclusion that the hybridization of the carbon bonding orbitals in cyclopropanes is close to sp2. The chemical shifts for several cyclopro pane hydrocarbons seem consistent with a ring current effects.
