| titleOfInvention | New thiol phosphoric acid esters |
| abstract | The invention comprises compounds of formula <FORM:0977819/C1/1> where R is secondary alkyl, R1 is C1- 4 primary alkyl and R2 is unsubstituted or substituted alkyl or aralkyl. They are prepared by reacting a phosphite (RO)(R1O)P(O)H with sulphur and an alkali to give the corresponding thiophosphoric acid salt which is then alkylated or aralkylated, e.g. with a halide or tosylate. Numerous examples are given in which R is isopropyl, sec-butyl or pinacolyl, R1 is methyl and R2 is ethylmercaptomethyl, ethylmercaptoethyl, cyanomethyl, cyanoethyl, p-chlorobenzyl, p-chlorophenylmercaptomethyl, N-methylcarbamoylmethyl, or 2-methylmercapto-5-methyl benzyl. R2 may also be arylmercaptoalkyl, alkylaminoalkyl, alkoxycarbonylalkyl, alkylmercaptocarbonylalkyl or dialkylcarbamoylalkyl. The products are pesticides. The ammonium salts of O-methyl-O-isopropyl, O-methyl-O-sec-butyl and O-methyl-O-pinacolyl thiophosphoric acids are prepared by reacting the corresponding secondary phosphites with sulphur and ammonia. Specification 685,737 is referred to.ALSO:Pesticidal compositions comprise thiophosphate esters of formula <FORM:0977819/A5-A6/1> where R is secondary alkyl, R1 is C1-4 primary alkyl and R2 is unsubstituted or substituted alkyl or aralkyl together with a solid or liquid carrier. Numerous examples are given in which R is isopropyl, sec-butyl or pinacolyl, R1 is methyl and R2 is ethylmercaptomethyl, ethylmercaptoethyl, cyanomethyl, cyanoethyl, p-chlorobenzyl, p-chlorophenylmercaptomethyl, N-methylcarbamoylmethyl, or 2-methylmercapto - 5 - methylbenzyl. R2 may also be arylmercaptoalkyl, alkylaminoalkyl, alkoxycarbonylalkyl, alkylmercaptocarbonyl-alkyl or dialkylcarbamoylalkyl. Other insecticides and/or fertilizers may be present. An emulsion containing a non-ionic emulsifying agent is specified. Specification 685,737 is referred to. |
