| Abstract: | The UV spectra of some ortho substituted aryl methyl sulphoxides are recorded and analysed. A comparison of the steric effects of ortho substituents on conjugation of CH3S-, CH3SO- and CH3SO2- groups with the para substituents in the benzene ring has been made. The ortho substituents do not inhibit conjugation in the case of sulphones while they cause a marked inhibition in the case of sulphides and sulphoxides. The inhibition of conjugation of the CH3SO- group under the influence of ortho substituents is observed when the CH3SO- group acts both as an electron donor and as an electron acceptor. An explanation is offered for the observed steric effects. |
