Summary of the InventionOrganic phosphoric acid ester derivatives of the formula wherein Rrepresents alkyl, R1represents alkyl, R2represents alkyl, alkenyl or alkynyl, R3represents alkyl or aryl, Xrepresents an oxygen atom or a sulfur atom and Yrepresents an oxygen atom, a sulfur atom or N―R4,in which R4represents alkyl, provided that in the case in which Y represents N―R4,then R3represents alkyl,and their use as insecticides and nematicides.

Oxime phosphate pesticidal compounds, compositions and methods

A class of compounds useful for providing long-term control of pests, such as insects, nematodes and acarids, having the structural formula: STR1 where R is lower alkyl, phenyl, substituted phenyl, naphthyl or substituted napthyl; R1 is hydrogen or C1 -C6 alkyl; R2 is C1 -C6 alkyl or phenyl; R3 is C1 -C6 alkoxy, C1 -C6 alkyl or C1 -C6 alkylthio; R4 is C1 -C6 alkoxy, C1 -C6 alkylthio, C1 -C6 alkylamino or C1 -C6 dialkylamino; and X is oxygen or sulfur.

Production of phosphoro chloride thiolates

A process for the production of a phosphoro chloride thiolate of the formula STR1 wherein R1 is alkyl, alkoxyalkyl, aryl, or aryl substituted by alkyl, alkoxy or halogen, and R2 is alkyl, comprising reacting a mixture of a dialkyl chlorophosphite of the formula and an alkyl dichloro-phosphite of the formula with a sulphenyl chloride of the formula to produce a mixture of a phosphorochloridothiolate of the formula STR2 and a phosphorodichloridothiolate of the formula STR3 and reacting the mixture without isolation with an alcohol of the formula in the presence of a dehydrochlorinating agent thereby to convert the phosphorodichloridothiolate of the formula STR4 to additional phosphorochloridothiolate STR5 The starting mixture is produced by reacting phosphorus trichloride with a trialkyl phosphite, or with an alcohol in the presence of a dehydrochlorinating agent.
