Dioxiranes are heterocyclic organic chemical substances that contain a three-membered ring consisting of two oxygen atoms and one carbon atom. The oxaziranes belong to the larger group of three-ring compounds with two heteroatoms in the ring. The dioxiranes can also be viewed as cyclic peroxides. As a result, many dioxiranes are only stable and very reactive in solution. Often the dioxiranes are only produced in situ and serve as oxidizing agents in organic chemistry .
Manufacturing
Dioxiranes are mostly synthesized from ketones and peracids (e.g. a salt of peroxomonosulphuric acid ). Dimethyldioxirane can be obtained by reacting acetone with a neutral buffered solution of potassium peroxomonosulphate (trade names including Oxone and Caroat):
use
Dimethyldioxirane and methyl (trifluoromethyl) dioxirane in particular have preparative importance as oxidizing agents .
