| titleOfInvention | NEW O-VINYL ESTERS WITH CARBALKOXY SUBSTITUTE FOR (THIONO) -THIOLPHOSPHORIC ACID, THEIR PREPARATION PROCESS AND THEIR APPLICATION AS INSECTICIDES |
| abstract | Thiolophosphates of formula (I) are new: In (I) X is O or S; R, R1, R2, R3 and R4 are each 1-6C alkyl). They are prepd. by reacting the corresp. phosphoryl halide with a 3-alkoxy-3-carbalkoxypyruvic acid ester (or its salts) opt. in a solvent and in presence of an acid acceptor. (I) are insecticides more active than known cpds. of similar structure. They have low phytotoxicity and may be used in plant protection, for hygienic applications and for preservation of stored goods. Residual activity on wood and clay is excellent and they are stable to alkali on white-washed surfaces. O-Ethyl, S-n-propyl, O-(1,2-dicarbethoxy-2-ethoxyviyl)thionothidophosphate was prepd. in 76% yield by reacting ethyl 3-carbethoxy-3-ethoxypyruvate and O-ethyl, S-n-proplyl thionothiolophosphoryl chloride in acetonitrile in presence of K2CO3. |
