Oxime chemistry
WebPhosgene oxime (CAS 1794-86-1; CX) has no known uses other than as a weapon of warfare. The potential use of phosgene oxime as a chemical terrorist weapon has recently increased. It is easy to synthesize and can exist in pure form as a white powder or yellowish powder depending on the impurities that are present. WebJun 27, 2024 · An oxime is formed by the reaction of hydroxylamine (NH2OH) with either an aldehyde or ketone. The oxime nitrogen has a double bond (sigma and pi) to the oxime carbon, a lone pair and a single (sigma) bond to the hydroxyl oxygen. If we use valence shell electron pair repulsion (VSEPR) theory to deal with the problem.
