P-Nitrocinnamic acid

Nitrobenzaldehyde has been prepared from -nitrotoluene by treatment with isoamyl nitrite in the presence of sodium methylate,1 by oxidation with chromyl chloride,2 cerium dioxide,3 or chromium trioxide in the presence of acetic anhydride.4 It can also be prepared by the oxidation of />-nitrobenzyl chloride,5 />-nitrobenzyl alcohol,6 or the esters of p-nitrocinnamic acid.7... [Pg.86]

Organic compounds containing carbon-carbon double bond (e.g. alkenes) can be reduced to the corresponding saturated compounds (eg., alkanes) by Pt02/H2, Pd/H2 or Raney Ni/H2. Even diimide is useful for reducing carbon-carbon double bond in compounds like p-nitrocinnamic acid, cyclohexene 1,2-dicarboxylic acid and oleic acid. [Pg.148]
