A 1-(3-pyridyl)-2,2,2-trihaloethyl compound of the formula I ##STR1## in which n is 0 or 1, R represents methyl and X is iodide, R' represents a radical of the formula II ##STR2## wherein V, Y and Z each represent a chlorine or bromine atom, A represents a radical of the general formula III ##STR3## in which B' is oxygen or sulphur and B stands for a member of the group consisting of an aliphatic radical having from 1-10 C-atoms of the group consisting of alkenyl radicals and alkyl radicals of the branched and straight chain type, the phenyl radical, an aralkyl radical having from 7-12 C-atoms and an amino group of the general formula IV ##STR4## in which F and D are identical or different, and represent a member of the group consisting of hydrogen, aliphatic radicals of the branched or straight chain type and having from 1-10 C-atoms, the phenyl radical, a substituted phenyl radical containing at least one substituent selected from the group consisting of lower alkoxy, lower alkanoyl, lower alkyl ester, COOH, halogen, lower alkyl, halo lower alkyl, nitro, and hydroxyl, and aralkyl radicals having from 7-12 C-atoms. A also representing a sulphonyl group of the general formula-SO.sub.2 -B, in which B has the same meaning as in formula III. The invention also relates to fungicidal compositions containing the compound according to the invention as active ingredients.

1-(3-Pyridyl)-2,2,2-trihaloethyl compounds and fungicidal compositions

1-(3-Pyridyl)-2,2,2-trihaloethyl compounds of the general formula I ##STR1## in which n is 0 or 1, R represents oxygen, hydrogen or an organic radical having at the most 12 C-atoms, m is 0 when R is oxygen, m is 1/2 or 1 when R is hydrogen or an aliphatic or aralkyl radical, and X represents a negative ion, R' represents a radical of the general formula II ##STR2## wherein V, Y, Z represent chlorine or bromine and may be identical or different, but are preferably identical; A represents hydrogen or a radical of the general formula III ##STR3## wherein B' is oxygen or sulphur, and B stands for an organic radical having up to 12 C atoms, or for an amino group of the general formula IV ##STR4## wherein F and D are identical or different, and represent hydrogen or organic radicals having at most 12 C-atoms; A may further be a sulphonyl group of the general formula --SO.sub.2 --B, in which B has the same meaning as in formula III. The invention also relates to a process of making the compounds, which are effective ingredients of fungicides and seed-dressing agents.
