INVESTIGATION AND SYNTHESIS OF ORGANOPHOSPHORUS COMPOUNDS
Abstract
INVESTIGATIONS DISCUSSED ARE: (1) the reaction between dialkyl alkylphosphonates and metallic Na; (2) methods for the synthesis of fluoroalkylphosphonates. (1)-Molten Na was dispersed in an inert hydrocarbon solvent at 110 degrees followed by the addition of the phosphonate ester. There were generally 2 principal products, one a gas and the other a solid. The reaction with metallic Na failed to take place with the trialkyl esters of phosphorous acid, the trialkyl esters of phosphoric acid, and the alkyl esters of dialkylphosphonic acids. All the phosphonic esters tried to date reacted readily. (3) Efforts to produce fluoroalkylphosphonate products were not successful. However, reactions of interest included the cleavage of diethyl trichloromethylphosphonate with KF dihydrate to give CCl4 as one product; a cleavage of diethyl trichloromethylphosphonate by anhydrous KF to give diethyl phosphorofluoridate.
