Abstract: 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

Abstract: 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.
