Phosgene mixed with water

The reaction of an organic substrate with phosgene is called phosgenation. Diols react with phosgene to give either linear or cyclic carbonates (R = H, alkyl, aryl): HOCR2−X−CR2OH + COCl2 → 1⁄n [OCR2−X−CR2OC(O)−]n + 2 HCl An example is the reaction of phosgene with bisphenol A to form polycarbonates.
