1.A study was made of the reaction of the acid chlorides of acetic, benzoic, ethylcarbonic and N-diethylaminosulfenic acids with the diethyl ester of methylurethanphosphorous acid. In all cases the reaction proceeds by the scheme of the Arbuzov rearrangement, with the formation of the corresponding phosphonic acid derivatives.2.The action of aqueous ammonia solution on the N-methylamide of ethylcarbonic and O-ethylbenzoylphosphonic acids at room temperature results in cleavage of the P-C and P-N bonds, and benzamide, the ammonium salt of ethylphosphorous acid and methylurethan are formed.3.The reaction of sulfur or selenium with the N-methylamide of ethylcarbonic and diethylphosphorous acids gave the N-methylamide s of the corresponding acids, namely of ethylcarbonic and diethylthiophos-phoric acids, and of ethylcarbonic and diethylselenophosphoric acids. |
