 Bis(trichloromethyl) Carbonate in Organic Synthesis)
Triphosgene (bis(trichloromethyl) carbonate (BTC) is a chemical compound with the formula OC(OCCl3)2. It is used as a solid substitute for phosgene, which is a gas. Triphosgene is stable up to 200 °C. Triphosgene is used in a variety of halogenation reactions. See more This compound is commercially available. It is prepared by exhaustive free radical chlorination of dimethyl carbonate: CH3OCO2CH3 + 6 Cl2 → CCl3OCO2CCl3 + 6 HCl Triphosgene can be … See more Triphosgene is used as a reagent in organic synthesis as a source of CO . It behaves like phosgene to which it cracks thermally: OC(OCCl3)2 → 3 … See more • Phosgene • Diphosgene See more Triphosgene's low vapor pressure makes it possible for it to reach concentrations that are considered toxicologically unsafe. While several properties of triphosgene are not yet readily … See more • Bulletin about Triphosgene • Material Safety Data Sheet See more WebWell-defined protocols and procedures, which allow efficient synthesis of a variety of described classes of organic compounds on a large scale, are now available, illustrating the synthetic and technological potential of BTC. Safe handling of solid BTC has been demonstrated, underlying the advantages over its gaseous cogener phosgene.
