An efficient and operationally simple method is developed for the syndesis of N, N-dialkyl phosphoramidic dichloride from dialkyl amine and phosphoryl chloride using basic anion exchange polymer resins/beads. In me reaction, polymer resin acts as a scavenger for HCl produced as by-product and desired product is distilled under vacuum. Reaction afforded N, N-dialkyl phosphoramidic dichloride in 3-4 hours with excellent yields from corresponding dialkylamine and phosphoryl chloride.
