摘要

2-Aryl or 2-heterocyclyl-2, 2-disubstituted ethyl-1,2,4-triazoles have been shown to have fungicidal activity. They have the formula wherein X is (C6-C10)aryl optionally substituted with up to three substituents, preferably with up to two substituents, which are independently hydroxy, halo, acetoxy, trihalomethyl, (C1-C4)alkyl, (C1-C4) alkoxy, (C1-C4)alkylthio, (C1-C4)alkylsulfinyl, (C1-C4)alkylsulfonyl, (C1-C4)-alkoxy(C1-C4)alkoxy, (C1-C4)alkylcarbonyl, (C2-C4)alkynyloxy, (C2-C8)alkenyl, (C2-C4)-alkenyloxy, (C2-C8)alkynyl, phenyl optionally monosubstituted with halo, alkyl or alkoxy, phenoxy optionally monosubstituted with halo, alkyl or alkoxy; or X is a 5 and 6 membered heterocyclic ring having up to three heteroatoms which are independently nitrogen, oxygen or sulfur, optionally substituted with up to two of (C1-C4)alkyl and/or halo, Q is 1-(1,2,4-triazolyl) or 4-(1,2,4-triazolyl) each optionally substituted with up to two substituents which are independently halo, (C1-C4)alkyl, nitro, cyano, mercapto or (C1-C5)alkylmercapto; Z is (C1-C12)alkyl, halo(C1-C12)alkyl, (C2-C8)alkenyl, halo(C2-C8)alkenyl, (C2-C8)alkynyl, (C3-C8)cycloalkyl, (C5-C8)cycloalkenyl, (C3-C8)cycloalkyl(C1-C6)alkyl, (C6-C10)aryl, (C7-C11)aralkyl, heterocyclyl as defined above for X or heterocyclyl(C1-C6)alkyl, provided X and Z are not both heterocyclyl groups; W is -OR, -OCOR'', -OCOY, -OCOR'Y, -OCOR'OR'', -OR'OCOR'', -OR'OR, -NH2, -NHCOR, -NHCOR'Y, -NHCOY, -OCONHY, -OSO2A, -OSiA3, -OPO(OA)2 or halo, wherein A is (C1-C6)alkyl; R is (C1-C12)alkyl, X, Y-alkyl, (C3-C8)alkenyl, (C3-C8)alkynyl, (C3-C8)cycloalkyl, cyano(C1-C6)alkyl or epoxy(C1-C6)alkyl, all optionally halogenated, or is hydrogen, provided that when Z is methyl, R is not haloalkyl; R' is (-CH(CH3)-)p(-CH2-)m or (-CH2-),CH=CH(-CH2-)t; m is an integer from 0 to 6; p is 0 or 1, provided m and p are not both 0; s and t are each independently integers of from 0 to 3; R'' is (C1-C2)-trialkylsilyl(C1-C4)alkyl, phenyl, (C1-C6)alkyl or (C2-C4)alkenyl, all optionally halogenated, or is hydrogen; R''' is hydrogen or (C1-C6)alkyl; n is an integer from 1 to 6; and Y is phenyl, naphthyl, piperidinyl, triazolyl, pyrazinyl, pyrimidinyl, phthalimido, morpholinyl, pyridyl, thienyl, furyl or (C3-C8)cycloalkyl, all optionally substituted with the substituents defined for X.
