Conclusions

  1. 1.

    An analysis of high-resolution NMR spectra in an aromatic fragment of phenyl alkyl ethers within a five-spin system was conducted.

     
  2. 2.

    A previous conclusion concerning the steric inhibition of coupling of the 2p electrons of the oxygen atom with theπ system of the aromatic ring in the case of tert-butoxybenzene due to steric perturbation of the p-π coplanarity of the molecule was confirmed.

     

The general similarity of the mechanism of the change in the constants of the1H-1H in phenyl ethers caused by steric perturbation of coupling in the phenoxy fragment and the competitive effect of the ether oxygen with a second unsaturated substituent was demonstrated.
