Koshel, S. G. published the artcileSynthesis of cyclohexylbenzoic acids by liquid-phase catalytic oxidation of cyclohexyltoluenes, Synthetic Route of 20029-52-1, the publication is Neftekhimiya (1989), 29(2), 257-61, database is CAplus.
Isomeric cyclohexyltoluenes were oxidized by mol. oxygen in glacial AcOH using Co(OAc)2 as catalyst and AcH as initiator. The reactivity of the cyclohexyltoluene decreased in the order: p– > m– > o-isomer.
Neftekhimiya published new progress about 20029-52-1. 20029-52-1 belongs to quinuclidine, auxiliary class Carboxylic acid,Benzene, name is 4-Cyclohexylbenzoic acid, and the molecular formula is C13H16O2, Synthetic Route of 20029-52-1.
