NEW MATERIAL:A trihaloallyl derivative of formula I (X is Br or I; R is cycloalkyoxymethyl, cycloalkylcarbonyl, 2-furoyl, 2-thenoyl, pyridylcarbonyl, phenoxycarbonyl, etc.). n EXAMPLE: 3-Cyclohexyloxymethoxy-1,1,2-triiodo-1-propene. n USE: Antifungal and preservative agent having high weatherability, especially excellent stability against light, and effective to various products for outdoor use. Effective for a long period. Also useful as an agricultural and horticultural miticide and insecticide. n PROCESS: The compound of formula I is prepared by reacting a trihaloallyl alcohol of formula II with an acid halide, a chlorocarbonic acid ester or a cycloalkyl chloro- methyl ether. Or an alternative method, the carbonate of the compound of formula I is prepared by reacting the compound of formula II with phosgene, and contacting the resulting compound of formula III with an alcohol. n COPYRIGHT: (C)1981,JPO&Japio |
