<p>Compounds of formula I <CHEM> wherein X is CH or N; n is 0, 1, 2 or 3; R<1> and R<3>, which may be the same or different, are alkyl, alkoxy or alkylthio, each of which is optionally substituted, halogen, nitro, cyano, COOR<4>, -NR<5>R<6>, CONR<5>R<6>, COR<7> or R<8>S(O)q; or R<1> and an adjacent R<3> group, or two adjacent R<3> groups, together with the carbon atoms to which they are attached can form a 5 to 8 membered ring which can include 1 to 3 heteroatoms and may be substituted; R<2> is an optionally substituted aliphatic hydrocarbon radical, which may be unsaturated, aryl or heterocyclyl; R<4> is hydrogen or an ester forming group; R<5> and R<6> are the same or different and are hydrogen, optionally substituted alkyl, acyl or aryl, or together with the nitrogen to which they are attached, form a 5 to 7 membered ring which can contain other hetero atoms; R<7> is hydrogen, optionally substituted alkyl or aryl; R<8> is optionally substituted alkyl or aryl; and q is 1 or 2, have fungicidal activity as do the intermediates of formula II <CHEM> wherein R<9> is hydrogen or methyl, and of formula III <CHEM> u</p> |
