Peroxide agents monoperoxyphthalic

So, when conducting the reaction at 65-85 °C in water, alcohol, ester, acetonitrile, the polyketone particles of size 0.01-100 micrometers transform the polyesters by the oxidation under the peroxide agents peroxy-benzoic, m-chloroperoxybenzoic, peroxyacetic, and triflouruperoxyacetic, monoperoxyphthalic, and monoperoxymaleine acids, combinations of H2O2 and urea or arsenic acid [405, 406]. 

Oxidation of quinazoline with various oxidizing agents, e.g. hydrogen peroxide, chromic oxide, peracetic acid, or monoperoxyphthalic acid, affords quinazolin-4(3//)-one in high yield. The reactive species is in fact the hydrated cation which is formed from quinazoline in the presence of even a trace of water and which is readily oxidized to the respective oxo compound (cf. p 161). 2-Substituted quinazolines react similarly, whereas when a substituent is present at C4, the hydrated cation is not readily formed and the more sensitive substituent is oxidized.
