Abstract:Flutriafol was a kind of broad-spectrum fungicide that could be used to control effectively cereal powdery mildew,cloud disease,leaf spot disease and rust disease. 1-o-fluorophenyl-1-p-fluorophenyl-2-chloroethanol was prepared through Grignard reaction starting with 2-fluorobenzyl bromide,and then reacted with sodium triazol to give the title product flutriafol. The total yield and purity were 59% and 94.5%,respectively.
