| titleOfInvention | Production of mesitylphosphonous acid dichloride |
| abstract | PURPOSE: To obtain the titled compound useful as an important intermediate in organic chemical industry, in high yield, by reacting bromomesitylene with alkyllithium, etc., under cooling and reacting the resultant lithiomesitylene with phosphorus trichloride under refluxing. n CONSTITUTION: The objective compound is produced according to the reaction formula, by (1) dissolving bromomesitylene in THF in an inert gas stream, (2) cooling the solution to e.g. -78°C, (3) adding a solution of an alkyllithium (e.g. n-butyllithium hexane) or metallic lithium to the solution and reacting e.g. for 1hr under stirring to produce lithiomesitylene, (4) adding phosphorus trichloride to the reaction system, (5) heating the system slowly to room temperature, (6) refluxing the reaction mixture e.g. at 70°C, (7) removing the precipitated lithium chloride, and (8) distilling the residue under reduced pressure. n COPYRIGHT: (C)1986,JPO&Japio |
