Abstract
NEW MATERIAL:The 3-ethyloxadiazole derivative of formulaI[X is group of formula II or formula III (X1WX4 are H, halogen, or CF3); R is alkyl, halogen- substituted alkyl, group of formula IV (R1 is halogen or alkyl; m is 0W2), -(CH2)nCOOR2 (R2 is H or alkyl; n is 0W3), or group of formula V (R3 and R4 are alkyl; A and B are or S)].
EXAMPLE: 5-Methyl-3-{1-[ 4-( 4-trifluoromethylphenoxy)phenoxy]ethyl}-1, 2, 4- oxadiazole.
USE: Herbicide harmless to the trnasplanted seedling of rice plant, and effective against Echinochloa oryzicola from the sprouting stage to the growing stage.
PROCESS: The compound of formulaIcan be prepared by (1) reacting the compound of formula VI with hydroxyamine, (2) reacting the product with the compound of R-C(=0)Cl, etc. in the presence of an acid acceptor, and (3) heating or refluxing the resultant compound of formula VII in the presence of acetic acid.
