ベンゼン置換体とクロラールの反応について (第6報)
Various substituent groups were introduced into anisole and acetanilide and their reactivity was compared by reacting with chloral in conc. sulfuric acid. The order of reactivity was OCH3>CH3>Cl>NHCOCH3>COOH>NO2 (in H2SO4). It is assumed that the reason why the acetamido group is placed lower than chlorine is because its polarization to Ar-NH+=C(CH3)-O-increases in conc. sulfuric acid.
