NEW MATERIAL:A compound shown by the formula I [X and Y are methyl, phenyl, or 4-chlorophenyl (one is methyl, and other is phenyl or 4-chlorophenyl); Z<1> and Z<2> are O, or S; R<1> and R<2> are alkyl]. EXAMPLE:Trans-4-( 4-chlorophenyl )-4-methyl-3-(O-ethyl-S-n-propylthiophosphoryl)- 2-thiazolidone. USE:An insecticde, acaricide, and nematocide. PREPARATION:For example, a compound [e.g., trans-4-(4-chlorophenyl)-5-methyl- 2-thiazolidone, etc.)] shown by the formula II is dissolved in a solvent such as THF, etc., and reacted with a compound (e.g., O-ethyl-S-n-propylthiophosphoric chloride, etc.) shown by the formula III (HAL is halogen) in the presence of n- butyl lithium, etc., to give a compound shown by the formula I . |
