Abstract
Fungicidal 3-amino-6-trifluoromethyl-2,4-dinitrodiphenylethers having the formula: ##STR1## where R is H or lower alkyl, PA1 X is halogen, PA1 n is 0, 1, 2 or 3, and PA1 R.sub.1 and R.sub.2 are selected from H and lower alkyl, or form a piperidinyl, morpholinyl, or pyrrolidinyl ring structure, Are prepared by two-step process involving reaction of 2,4-dichloro-3,5-dinitrotrifluoromethylbenzene with an amine, and condensation of the intermediate with a phenol. The compounds of the invention show good fungicidal activity against bean mildew, bean rust and tomato blight, and insecticidal activity against Mexican bean beetle.
