NEW MATERIAL:A compound shown by formula I (X is halogen or phenyl; m is 1 or 2; n is 0W2; A is N or CH). n EXAMPLE: 1-(4-Chlorobenzyl)-2-(1H-1,2,4-triazol-1-ylmethyl)cyclopentane-1-ol. n USE: An agricultural and horticultural fungicide having low toxicity and high safety. n PREPARATION: A cyclopentanone derivative [2-(1H-1,2,4-triazol-2-yl-methyl) cyclopentanone, etc.] shown by formula II is reacted with a Grignard reagent shown by formula III (Y is halogen) to give a compound shown by formula I. The starting raw material shown by formula II is a novel compound and is produced by reacting a ketone shown by formula IV (R is eliminable group such as halogen, methanesulfoxy, p-toluenesulfoxy, etc.) with a 1,2,4-triazole or imidazole shown by formula V in the presence of a diluent. n COPYRIGHT: (C)1988,JPO&Japio |
