Conformational Studies of Some Substituted Aryl Quinolyl Sulphones

2-(4-methoxyphenylsulphonyl)-4-methylquinoline (2), 2-(4-methylphenylsulphonyl)- 4-methylquinoline (4), 2-(4-methylphenylsulphonyl)- 3,4-dimethylquinoline (6), 2-(4-methylphenylsulphonyl)-3- -ethyl-4-methylquinoline (8) and 2-(4-methylphenylsulphonyl)-4- -methyl-6-methoxyquinoline (10) have been synthesised by permanganate oxidation of the corresponding sulphides 1, 3, 5, 7 and 91•2 •3• This conversion was confirmed through elemental analyse$ and ir and NMR spectral data (c. f., Tables-I and II). Comparative NMR spectral studies have been done and the structures of 1 - 10 have been established (c. f. , Table-II)
