Electronic structure of substituted phenylisoxazoles and substituted isoxazolines is examined by35Cl NQR and MINDO/3 calculations. It is shown that the chlorine atom in the 4-position of the isoxazole ring serves to transmit the influence from the phenyl ring in the 3-position to that in the 5-position. The influence is transferred via both the σ- and π-bond systems.
