Lead halophenoxides and carbonylation catalyst and method for preparing and employing them |
| abstract |
Lead halophenoxides, especially bromophenoxides, are prepared by the reaction of lead(II) oxides with a hydroxyaromatic compound such as phenol and a chloride or bromide salt such as an alkali metal bromide, a tetraalkylammonium bromide or a hexaalkylguanidinium bromide. They are useful in catalyst compositions for the oxidative carbonylation of hydroxyaromatic compounds to diaryl carbonates. |
