In the bromination of benzene using Br_2 and FeBr_3, is the intermediate carbocation aromatic? Explain. Why is the aromatic ring of a phenolate anion more strongly activated toward electrophilic substitution than the aromatic ring of phenol?
NaOH and HCl were used to adjust the pH of the solutions. The initial pH of solutions with test TCs was 4.25 without pH adjusting. The effects of ions (CO32−, HCO3−, NO3−, SO42−, and NH4+) on test TCs attenuation under UV, H2O2/UV, and Fe(II)/UV treatments were ...
Topic: Amine and Heterocyclic reaction (Read 12437 times) CH3CH2NH2 + CH3CO-O-COCH3 --> CH3CH2-NH-COCH3 + CH3COOH Question: explain why only one amine hydrogen which is get substituted by acetyl group eventhough acetate anhydride is used excessively in the reaction??

University of Tübingen, Tübingen, Germany INTRODUCTION Towards the end of the second World War we attempted the preparation of cyclohexanone-oxime (an important intermediate in the synthesis of Perlon) starting from cyclohexane-that means benzene as the basis, by avoiding the then scarce phenol ...
