The author of 《Substitution products of 4-hydroxybenzophenone and of its methyl ether》 were Blakey, Wm.; Jones, W. I.; Scarborough, H. A.. And the article was published in Journal of the Chemical Society in 1927. Category: chlorides-buliding-blocks The author mentioned the following in the article:
4-Acetoxybenzophenone m. 81°. 4-MeOC6H4Bz with Cl in AcOH gives the 3-Cl derivative, m. 98°; further chlorination gives the 3,5-di-Cl derivative, m. 74° (α-oxime, m. 146°); 3,5-dichloro-4-methoxybenzanilide, pale yellow, m. 154°, from the oxime and PCl5; hydrolysis gives PhNH2 and 3,5-dichloroanisic acid, m. 202°. 3,5-Dichloro-4-hydroxybenzophenone, from the Me ether or by passing Cl into 4-HOC6H4Bz, m. 148°. 3-Bromo-4-methoxybenzophenone, m. 94°, from 4-MeOC6H4Bz and Br in AcOH-AcONa, at 100°, in the cold or in bright sunlight; α-oxime, m. 164°; 3-bromo-4-methoxybenzanilide, m. 170°; β-oxime, m. 111.5°, transformed into benzo-3-bromo-4-methoxyanilide, m. 156°. 3-Chloro-5-bromo-4-methoxybenzophenone, m. 92°. 4-MeOC6H4Bz and ICl in AcOH give the 3-I derivative, m. 81°; α-oxime, m. 182°, converted to 3-iodo-4-methoxybenzanilide, yellow, m. 206°. The β-oxime, m. 135°, yields benz-3-iodo-4-methoxyanilide, m. 164°. 3-Iodo-4-hydroxybenzophenone, m. 184°; the 3,5-di-I derivative, m. 145°, is formed from 4-HOC6H4Bz and ICl in AcOH-AcONa. Nitration of 4-MeOC6H4Bz gives the 3-NO2 derivative, yellow, m. 105°; α-oxime, yellow, m. 179°, yielding 3-nitro-4-methoxybenzanilide, m. 163°. 3,5-Dinitro-4-methoxybenzophenone, yellow, m. 105°, from the 4-Cl derivative and MeONa. The 4-HO derivative, yellow, m. 138°. 3′-Nitro-4-methoxybenzophenone, pale yellow, m. 95°, from m-O2NC6H4COCl and PhOMe with AlCl3 in CS2; nitration gives the 3,3′-dinitro derivative, pale yellow, m. 143°; this also results from 4-MeOC6H4Bz and HNO3. 3,3′-Dinitro-4-hydroxybenzophenone, pale green, m. 165°. 3,4′-Dinitro-4-methoxybenzophenone, m. 174°, by nitrating the 4′-NO2 derivative 3,3′,5-Trinitro-4-methoxybenzophenone, m. 184°, forms about 65% of the nitration product from 4-MeOC6H4Bz with H2SO4 and HNO3 for 2 days or from the 3,5-di-NO2 derivative; the 3,3′-di-NO2 derivative gives almost quant. the 3,3′,5-tri-NO2 derivative From the crude nitration product there were also isolated 2′(?),3-dinitro-4-methoxybenzophenone, m. 125°, and the 2′(?),3,5-trinitro derivative, light yellow, m. 142°. In the part of experimental materials, we found many familiar compounds, such as 3,5-Dichloro-4-methoxybenzoic acid(cas: 37908-97-7Category: chlorides-buliding-blocks)
3,5-Dichloro-4-methoxybenzoic acid(cas: 37908-97-7) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Organochlorine compounds have wide use in many applications, though some are of profound environmental concern, with TCDD being one of the most notorious.Category: chlorides-buliding-blocks
