Three new aryl sulphonylacetic acids have been prepared from 2-chlorotoluene, 1,2-dichlorobenzene and 1-bromonaphthalene. The infrared spectra of these acids exhibited strong bands characteristic of carbonyl stretching frequencies of carboxylic acids. Utilising these sulphonylacetic acids some new unsaturated sulphones were synthesised. An attempt has been made to correlate the infrared and proton magnetic resonance spectral data to the configurations of unsaturated sulphones.
