Abstract

The carbon‐13 NMR spectra of a series of exo‐and endo‐epimers of 2‐substituted benzonorbornene (2‐substituent = OH, OCHO, Br, NH~2~, NHMe or NMe~2~) have been examined. The spectra are readily assigned by comparison with the coupled and off‐resonance proton decoupled spectra as well as by the use of shift reagents. Interesting and diagnostic features of the spectra allow the distinction between epimers.

## Abstract The ^13^C NMR spectra of all azabenzenoid isoxazolopyridines and some of their chloro derivatives are discussed. All ^13^C resonances were unambiguously assigned by means of gated decoupled spectra, from which one‐bond and long‐range ^13^C^1^H coupling constants have been determined fr

## Abstract Carbon‐13 NMR spectra of a series of benzylphenols and their __O__‐alkylated derivatives were recorded to find the substituent effects of the benzyl, hydroxybenzyl and alkoxybenzyl groups on the ^13^C chemical shifts. It was found that the methylene bridge carbons show signal shifts mai

## Abstract ^13^C chemical shifts and ^13^C–^31^P coupling constants are reported for nineteen pyrazoles bearing an NPPh~3~ substituent at position 5. The three heterocyclic carbons are coupled with the phosphorus (^2^__J__, ^3^__J__ and ^4^__J__). These couplings are very sensitive to the nature
