Abstract

1330788 Unsaturated phosphorus esters SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 1 March 1972 [3 March 1971] 5900/71 Heading C2P Vinyl phosphorus esters of the general formula wherein R 1 and R 2 are alkyl or aryl, R 3 , R 4 and R 5 are H, halogen or alkyl, X is O or S, and Y is a covalent bond or an O or S atom are obtained by dehydrohalogenating a phosphorus ester of the formula wherein one of A and B is H and the other is halogen using an alkali metal alkoxide, preferably one derived from a tertiary alcohol having up to 6 carbon atoms, e.g. potassium t-butoxide. The alkoxide suitably dissolved in an excess of the corresponding alkanol may be added slowly to the starting ester which is preferably dissolved in an organic solvent, e.g. benzene, diethylether or dimethylsulphoxide. Alternatively, an alkali metal hydroxide may be added to a solution of the starting ester in the appropriate alcohol. The reaction temperature is suitably maintained at 0-5‹ C. during the addition of the base, e.g. by use of external cooling. Compounds in which R 1 and R 2 are alkyl, R 3 is halogen, R 4 is H, R 5 is H or halogen, X is O or S and Y is an oxygen atom are stated to be novel and the invention includes such compounds per se. The novel compounds have pesticidals, especially insecticidal and acaricidal properties and may be used as active ingredients in pesticidal compositions of conventional type. 1,2,2 - Trichloroethylphosphorodichloridate is obtained by passing gaseous O 2 into a mixture of PCl 3 and trans 1,2-dichloroethylene at -10‹ to - 5‹ C. The product on reacting with ethanol under nitrogen at 0-5‹ C. yields diethyl 1,2,2- trichloroethyl phosphate. When the same product is reacted with P 2 S 5 at 150-170‹ C. under nitrogen followed by reaction with methanol, dimethyl 1,2,2-trichloroethyl phosphorothionate is obtained.
