Trichloroethylene

An epoxide (l 2 2-trichlorooxirane) was postulated as an intermediate during the oxidation of trichloroethylene to chloral hydrate however later studies on the biotransformation of trichloroethylene and other chlorinated olefins and knowledge of the mechanisms of oxidation by cytochrome P450 enzymes suggest a stepwise oxidation of trichloroethylene to chloral hydrate in which the epoxide is
