| titleOfInvention | Dithiophosphoric ester derivative, its preparation, insecticide and acaricide comprising it as active ingredient |
| abstract | NEW MATERIAL:A compound shown by the formulaI(R 1 , R 3 , and R 4 are lower alkyl; R 2 is H, lower alkyl). n EXAMPLE: O, O-Dimethyl S-[ ( 1-dimethoxymethyl-2-carbomethoxy )ethyl ]phosphorodithioate. n USE: An insecticide and an acaricide. n PROCESS: An unsaturated ester (e.g., 4,4'-dimethoxycrotonic acid methyl ester, etc.) shown by the formula II is reacted with a dithiophosphoric acid (alkali metal salt) shown by the formula III (M is H, alkali metal), preferably in a molar ratio of (1:1)W(1:1.2), for example, in the presence of a basic compound, such as KOH, etc. in a solvent such as methanol at 0°CW room temperature for 0.5W 2hours. n COPYRIGHT: (C)1982,JPO&Japio |
