Studies of aromaticity by nuclear magnetic resonance spectroscopy. IV. The proton chemical shifts in Cycl[3,2,2]azine

Abstract

The n.m.r, spectra of cycl[3,2,2,]azine and some derivatives have been examined. The spectral assignments made by Boekelheide at al. for cycl[3,2,2]azine hare been confirmed by arguments which are independent of MO calculations. SCFMO calculations of the proton chemical shifts in cycl[3,2,2]azine are in reasonable agreement with the observed values.
