Abstract

The invention comprises 1-isonicotinyl-2-acyl-hydrazines of the general formula <FORM:0714231/IV (b)/1> wherein R stands for an aliphatic carboxylic acyl radical (e.g. alkanoyl, substituted alkanoyl, alkenoyl and substituted alkenoyl) or an aromatic carboxylic acyl radical (e.g. benzoyl and substituted benzoyl). The compounds are prepared by reacting isonicotinyl-hydrazine with an acid halide or with an acid anhydride of the formul R-Hal or R-O-R respectively. The examples describe the preparation of 1-isonicotinyl - 2 - acetyl - hydrazine, 1 - isonicotinyl - 2-propionyl - hydrazine, 1 - isonicotinyl - 2-butyryl - hydrazine, 1 - isonicotinyl - 2 - (b -carboxy - acryloyl) - hydrazine, 1 - isonicotinyl-2 - benzoyl - hydrazine, 1 - isonicotinyl - 2 - (2-carboxy - benzoyl) - hydrazine, 1 - isonicotinyl-2 - stearoyl - hydrazine, 1 - isonicotinyl - 2-palmitoyl - hydrazine, 1 - isonicotinyl - 2-lauroyl - hydrazine, 1 - isonicotinyl - 2 - D 9-undecenoyl - hydrazine, 1 - isonicotinyl - 2-phytanoyl - hydrazine (the picrate of which is described), 1 - isonicotinyl - 2 - (21,41,61 - trimethyl - benzoyl) - hydrazine and 1 - isonicotinyl - 2 - (21,31,51 - trichloro - benzoyl)-hydrazine.
