This shows that a high concentration of HCl does not favour oxidative polymerisation of phenylamine, even though the ammonium persulphate/HCl system is widely used in polyaniline synthesis. On the basis of the experimental data and density functional theory for reaction path modelling, we proposed a...
Reaction: Procedure: 1. In a 100 mL conical flask place 20 mL of water, 5 mL conc. HCl and 3.5 g aniline. 2. Shake vigorously and add about 15 g crushed ice. 3. In a test tube dissolve 1.3 g sodium nitrite in 3 mL water. 4. Add this sodium nitrite solution 1803 Words 8 ...
after the end of the reaction, add 5ml of water and stir with a glass rod (usually a tertiary amine is added to neutralize the acid produced): ch3coh5cl c6nh2 → CH3CONHC6H5 HCl3, acetic anhydride aminolysis in aniline (usually a tertiary amine is added to neutralize the acid produced...

- Aniline (C6H5NH2) is treated with HCl and NaNO2 at a low temperature (0-5°C). - This reaction forms a diazonium salt (C6H5N2+Cl−) through the following reaction: C6H5NH2+HCl+NaNO2→C6H5N+2Cl−+NaCl+H2O Step 2: Formation of Bromobenzene ...
Preparation of aniline from nitrobenzene Mechanism: (i) 3Fe+6HCLrarr3FeCl(2)+6H (ii) C(6)H(5)NO(2)+6HrarrC+6H(5)NH(2)+2H(2)O (iii) FeCl(2)+2H(2)OrarrFe(OH)(2)+2HCl (iv) C(6)H(5)NO(2)+2Fe(OH)(2)+4H(2)OrarrC(6)H(5)NH(2)+Fe(OH)(3)
A similar mechanism to that from above is likely operative and the reaction has a similar functional group tolerance. The t-butyl protecting group was removed by stirring the indole with 1M HCl in MeCN at room temperature overnight (98% yield). When treated with hexafluoroisopropanol in TFA, ...
The preparation and biological activity of BAP derivatives inspired the preparation of N6-phenyladenines and its ring substituted derivatives. Unsubstituted N6-phenyladenine was synthesized for the first time by direct reaction of 6-methylsulfanylpurine and aniline at high temperature [72]. Later, it...
