Process for the production of aldehydes or ketones by oxidative cleavage of olefinic double bonds by means of a coordination complex of a ligand and a peroxo derivative of a metal of group 6b. Aldehydes and ketones obtained by said process are used among others as intermediates in the synthesis of organic products.

Process for the production of aldehyde or ketone compounds and aldehydes

A process for the preparation of isosorbide-2-mononitrate (I) ##STR1## from isosorbide-2,5-dinitrate (II) ##STR2## The isosorbide-2,5-dinitrate (II) is treated, in a reaction medium consisting of an aqueous organic solvent, with salts of metals of low oxidation state. Isosorbide-2-mononitrate (I) is obtained with high selectivity.
