Highly efficient and stable peracid for rapid and selective oxidation of aliphatic amines to oximes
A novel, transition-metal free, rapid approach for selective oxidation of aliphatic and benzylic amines to oximes is described. The dodecanebis(peroxoic acid)-DMF combination efficiently oxidizes various aliphatic amines at 50 °C temperature to give 100% conversion in 20 min with high oxime selectivity. The peroxy acid used here shows exceptional stability at room temperature and is non-shock sensitive in nature, which was confirmed by differential scanning colorimetric (DSC) analysis.

SELECTIVE MIXED COUPLING OF CARBOXYLIC ACIDS-III. SYNTHESIS OF CYCLOPENTADECANONE FROM CYCLIC TETRAACYL DIPEROXIDES
Cyclopentadecanone (1b) and cyclotetradecane (1a) were prepared in 53 and 83percent yield by thermolysis or photolysis of the cyclic tetraacyl diperoxides 4b and 4a.The compounds 4a, b were obtained from diperoxydodecanedioic acid (3) and the acyl chloride 5a or the dicarboxylic acid 2b.

Process for the manufacture of peroxycarboxylic acids
Peroxycarboxylic acids are prepared by the oxidation of a fatty acid with an excess of hydrogen peroxide in the presence of a strong acid catalyst. The yield is improved and the reaction time is reduced by intimately dispersing throughout the reaction mixture an inert water immiscible solvent for the peroxycarboxylic acid. The product may be recovered in crystalline form from the solvent phase.
