Oxidation of toluenes to aromatic aldehydes with molecular oxygen in subcritical water

摘要

Oxidations are important transformations in organic synthesis.In general,many oxidations are carried out with a large excess of chromium or manganese reagents.The metal residues are environmentally undesirable and often cause problems during work-up.In addition organic oxidations in the chemical industry have traditionally been performed in either aromatic or halo-genated solvents.One of the most attractive oxidants is molecular oxygen,since oxygen is highly soluble in subcritical water.
