Compounds of formula I
wherein X is CH or N; n is 0, 1, 2 or 3;
R¹ and R³, which may be the same or different, are alkyl, alkoxy or alkylthio, each of which is optionally substituted, halogen, nitro, cyano, COOR⁴, -NR⁵R⁶, CONR⁵R⁶, COR⁷ or R⁸S(O)q; or R¹ and an adjacent R³ group, or two adjacent R³ 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;
R² is an optionally substituted aliphatic hydrocarbon radical, which may be unsaturated, aryl or heterocyclyl;
R⁴ is hydrogen or an ester forming group;
R⁵ and R⁶ 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;
R⁷ is hydrogen, optionally substituted alkyl or aryl;
R⁸ is optionally substituted alkyl or aryl; and
q is 1 or 2, have fungicidal activity as do the intermediates of formula II
wherein R⁹ is hydrogen or methyl, and of formula III
