NEW MATERIAL:Compounds of formula I (R is γ-fluoropropyl, β-fluoroisopropyl; X is methyl, trifluoromethyl). n EXAMPLE: 3'-(γ-Fluoropropxy)-2-methylbenzanilide. n USE: Aquatic life repellent, especially effective on shells like barnacles. n PREPARATION: The reaction of a compound of formula II such as 3'-hydroxy-2- methylbenzanilide with a fluoropropyl halide of formula: HalR (Hal is halogen) such as 1-bromo-3-fluoropropane is effected in the presence of a dehalogenating agent such as pyridine, triethylamine to give the compound of formula I. The suitable selection of solvent from usual ones is preferred in order to proceed the reaction smoothly. n COPYRIGHT: (C)1981,JPO&Japio |
