Abstract
A process for the formation of pentaerythritol-based phosphorus heterocycles comprises the reaction of a pentaerythritol polyol, e.g., pentaerythritol, with a trivalent or pentavalent phosphorus compounds, e.g., a phosphorus oxytrihalide, a triorganophosphite, or a phosphorus trihalide, in an aryl phosphate solvent at elevated temperature.
