Abstract

^1^H and ^13^C NMR spectra of symmetrically substituted cyclotriphosphazenes exhibit second‐order effects. The influence of the ^31^P,^31^P coupling constants between ring phosphorus atoms on these effects was studied. Some values of this coupling constant between phosphorus bearing identical substituents were measured using ^13^C satellites of the ^31^P signals or by introduction of a chiral substituent on the third phosphorus atom.

## Abstract The ^31^P^31^P and ^13^C^31^P coupling constants in 1,6‐diphosphatriptycene have been obtained from analysis of its proton decoupled ^13^C n.m.r. spectra. More accurate data, however, resulted from simultaneous analysis of the proton decoupled ^13^C spectra and ^31^P(^13^C) satellite

## Abstract The ^13^C—^31^P coupling constant is much larger for a 2‐methyl substituent (about 20 Hz) than for a 3‐methyl substituent (about 5 Hz) in phospholes and 2‐phospholenes, and appears useful for assigning structures in these compounds.
