A systematic study has been made of the synthesis of dipropylaniline from aniline and n-propanol using H2SO4 and HCl as catalysts. With both catalysts, the optimum temperature, pressure, residence period, mole ratio of aniline to n-propanol and mole ratio of aniline to H+ (catalyst) for ...
Reaction of 1-naphthylamine with ethyl benzoylacetate gives the corresponding benzoyl acetamide derivative 1, which undergoes cyclization to 4-phenylbenzo[h]quinolin-2(1H)-one (2) in the presence of H2SO4. Bromination with POBr3, followe... S Facchetti,V Jurcik,S Baldino,... - 《Organomet...
Albrecht [J Am Chem Soc 82 3813 1960] obtained spectroscopically pure material by heating with charcoal to 50-60o, filtering and adding 2,4-dinitrophenylhydrazine and a few drops of conc H2SO4. After standing for several hours, the mixture is cooled to 0o, filtered and distilled in a ...
