What are described are insect- and mite-repellent compositions comprising at least 2 enantiomers selected from the group of 1-[(S)-sec-butyloxycarbonyl]-2-(S)-(2-hydroxyethyl)piperidine (referred to hereinafter as S,S), 1-[(R)-sec-butyloxycarbonyl]-2-(R)-(+)-(2-hydroxyethyl)piperidine (referred to hereinafter as R,R), 1-[(S)-sec-butoxycarbonyl]-2-(R)-(+)-(2-hydroxyethyl)piperidine (referred to hereinafter as S,R), 1-[(R)-sec-butyloxycarbonyl]-2-(S)-(+)-(2-hydroxyethyl)piperidine (referred to hereinafter as R,S), excluding the racemate mixture thereof, a process for preparation thereof and the use thereof in insect- and mite-repellent formulations.

Synergistically active mixtures of &#x3b1;,&#x3c9;-amino alcohol enantiomers, preparation thereof and use thereof in insect- and mite-repellent formulations

A process for preparing benzomorpholine derivatives is described, in which an o-nitrophenoxy carbonyl compound is hydrogenated in the presence of extraneous metal-doped sponge metal catalysts based on nickel or cobalt with ring formation.

Process for preparing benzomorpholine derivatives by hydrogenating o-nitrophenoxy carbonyl compounds

A process for preparing acyl amide compounds is described, in which a recrystallized o-nitrophenoxy carbonyl compound is hydrogenated with hydrogen gas in the presence of a nickel sponge metal catalyst with ring closure to form a benzoxazine, which is then reacted with an acyl halide to give the corresponding acyl amide compound.
