Title: Sulfamoylphenyl esters of organic phosphorothioates
IPC: C07F9/12
Filed: 1960-05-30
Abstract: The invention comprises a sulphamoylphenyl phosphate or thiophosphate of the formula:- <FORM:0917948/IV (b)/1> wherein each R1 is the same or different and is a C1-C4 alkyl radical, A is an oxygen or sulphur atom and each R2 is the same or different and is a hydrogen atom or a C1-6 alkyl radical. The products may be obtained by (a) condensing under alkaline conditions a 1-phenol-4-sulphonamide of the formula: <FORM:0917948/IV (b)/2> with a phosphorus compound of the formula (K)(K)Y.X where X is chlorine or bromine, K is chlorine, bromine or -OR1 (where R1 <FORM:0917948/IV (b)/3> is as defined above) and Y is or <FORM:0917948/IV (b)/4> to form a compound of the formula: <FORM:0917948/IV (b)/5> (b) and when K is Cl or Br treating with R1OH in the presence of an acid acceptor to convert K into -OR1, (c) and when Y is <FORM:0917948/IV (b)/6> treating with sulphur or an oxidising agent, e.g. dinitrogen tetroxide to convert into <FORM:0917948/IV (b)/7> or <FORM:0917948/IV (b)/8> respectively. The condensation in step (a) is preferably carried out in the presence of a solvent e.g. water, acetone, methyl ethyl ketone, or toluene and at between 0 DEG C. and 100 DEG C. The phosphorothioate products may be converted to the corresponding phosphates by treating with various oxidising agents, thus O,O-diethyl-p-sulphamoylphenyl phosphorothioate may be treated with nitric acid at below 20 DEG C. to form the corresponding phosphate. Several examples are given including the production of O,O-dimethyl-O-p-sulphamoylphenyl phosphorothioate by first reacting the sodium salt of 1-phenol-4-sulphonamide with thiophosphoryl chloride in the presence of a small amount of phosphorus trichloride to form O-p-sulphamoylphenyl phosphorodichloridothioate and then reacting the latter with two equivalents of methanol in the presence of triethylamine. The products have insecticidal and parasiticidal properties (see Group VI).ALSO:An insecticidal composition, or a parasiticidal composition suitable for oral or parenteral administration to warm-blooded animals, contains as active ingredient a sulphamoylphenyl phosphate or thiophosphate having the formula <FORM:0917948/VI/1> wherein each R1 is the same or different and is a C1-C4 alkyl radical, A is an oxygen or sulphur atom and each R2 is the same or different and is a hydrogen atom or a C1-C6 alkyl radical (see Group IV (b)). When the composition is to be adminstered orally it may be in the form of a capsule or tablet or it may be administered as a drench or by incorporation in feed, salt, or drinking water. It may also be in the form of a solution, emulsion, suspension or wettable powder. Specified carriers are talc, clays, diatomaceous earth, attapulgus clay, fuller's earth, pyrophyllite and acetone.
