Studies in the norbornene series. Part I. Elucidation of the structure of norbornene derivatives by use of the nuclear magnetic resonance shift reagent trisdipivaloylmethanatoeuropium(III), the nuclear Overhauser effect, and mass spectrometry

Abstract

An assessment of n.m.r. and mass spectral methods shows that the nuclear Overhauser effect and the shift reagent trisdipivaloylmethanatoeuropium(III) are particularly valuable in assigning the structure and stereochemistry of substituted norbornenes and of norbornanes carrying a fused heterocycle. Mass spectra support the structural assignments.
