- Process for the continuous preparation of amino-halo-genophenyl alkyl thioethers
-
Amino-halogenophenyl alkyl thioethers prepared in an advantageous manner by catalytic reduction of the corresponding nitro compound by the nitro compound being continuously hydrogenated with hydrogen in the presence of a supported noble-metal catalyst.

- Process for the preparation of 2-amino-6-chlorophenyl-alkylsulfanes, and 2-amino-6-chlorophenyl-isopropylsulfane
-
2-Amino-6-chlorophenyl-alkylsulfanes are prepared in a particularly advantageous manner by hydrogenating 2-chloro-6-nitrophenyl-alkylsulfanes catalytically in the presence of a solvent without the addition of a further sulfur compound, and the novel compo

- The chemistry of benzothiadiazole plant activators
-
Systemic Acquired Resistance (SAR) is an inducible resistance mechanism in plants that, together with other defence mechanisms, provides broadspectrum and long-lasting disease control. With novel screening techniques the benzo[1,2,3]thiadiazole-7-carboxylic acid derivatives have been identified as a new class of chemicals which stimulate the plant's own defence mechanisms. The synthesis and biological activities of various benzo[1,2,3]thiadiazoles and related structures are described. S-Methyl benzo[1,2,3]thiadiazole-7-carbothioate is the first synthetic chemical 'plant activator' that has been developed for this novel disease control concept.
