Molecule Structure Image



Triphosgene is a chemical compound that is used as a safer substitute for phosgene, because at room temperature it is a solid crystal, as opposed to phosgene which is a gas. It is used in organic synthesis to bond one carbonyl group to two alcohols, as in the synthesis of octalactin B. It is prepared by exhaustive chlorination of dimethyl carbonate.
