WebbThe color-substance, C9H9O5N2K, (III) was successfully isolated from the Janovsky reaction-mixture of acetone, m-dinitrobenzene (I), and potassium hydroxide. The spectral and chemical properties were studied in comparison with the potassium salt of 2, 4-dinitrobenzyl methyl ketone (V), the Meisenheimer-like complex structure of III being … Webb1 jan. 1989 · The photochemical isomerization reaction of [Co(NH 3) 5 NO 2]Cl 2 to [Co(NH 3) 5 ONO]Cl 2 has been studied in the solid state by means of i.r. spectroscopy. The reaction is first order with k = 2.53±0.05 × 10 −4 s −1 and is much faster (t 1 2 =49min) than the well-known spontaneous nitrito → nitro isomerization (t 1 2 = 6 days). The i.r. …

WebbThe carbon para to the nitro group is more reactive because the negative charge that is created can be delocalized into the nitro group. What is an electrophilic aromatic substitution? the reaction between a nucleophilic aromatic ring and an electrophilic reagent. As a nucleophile, electron donating groups on the aromatic ring increase reactivity.
