Kohlrausch, K. W. F. published an article in 1947, the title of the article was Studies of Raman effect. CLXXIII. Benzene derivatives. 30. Interpolated Raman spectra.Computed Properties of 452-75-5 And the article contains the following content:
Since a stepwise substitution of X = NH2, OH, Me, Cl, Br, I produces a regular frequency transition from one derivative to another, the spectra of members of the series not yet determined or undeterminable for any reason can be determined by interpolation. This is done for m- and o-C6H4(NH2)2, NH2C6H4OH, NH2C6H4F, FC6H4OH, BrC6H4OH, FC6H4Br, IC6H4NH2, IC6H4OH, IC6H4F, IC6H4Br, C6H4I2 1,3,5-F3C6H3, 1,3,5-Me2FC6H3, 1,3,2-Me2FC6H3, 1,2 3-Me2FC6H3, 1,3,4-Me2FC6H3, 1,2,4-Me2FC6H3, 1,4,2-Me2FC6H3, 1,4,2-MeClFC6H3, 1,4,2-Cl2FC6H3, 1,3,4-Cl2FC6H3. The experimental process involved the reaction of 4-Chloro-2-fluorotoluene(cas: 452-75-5).Computed Properties of 452-75-5
4-Chloro-2-fluorotoluene(cas:452-75-5) belongs to chlorides. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.
