The synthetic route for a halo-substituted thiophenylethyl variant of blasticide carpropamid is described. First, halo-substituted acetylthiophene was homologated to thiophenylacetic acid using Pb(OAc)4 and BF3OEt2, followed by reduction to CH2CH2OH with NaBH4/I2 or BH3Me2S, and then to the azide via the tosylate. The azide was transformed to the amine using triphenylphosphine, which was then allowed to react with the corresponding acyl chloride to yield the final amide product. Fungicidal tests of 50 related products for gray mold and downy mildew on cucumber, and leaf rust and powdery mildew on wheat were conducted in 500 mg/l on pot. Many compounds showed efficacy to control these plant diseases. It should be noted that several blasticide-oriented compounds displayed high control effectiveness on downy mildew. In the experiment, the researchers used 2-(2-Chlorothiazol-5-yl)acetonitrile(cas: 865660-15-7Quality Control of 2-(2-Chlorothiazol-5-yl)acetonitrile)
2-(2-Chlorothiazol-5-yl)acetonitrile(cas: 865660-15-7) is a member of organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. They are generally not present in crude oils and are typically the result of additives, cleaning solutions or chemicals used for oil recovery.Quality Control of 2-(2-Chlorothiazol-5-yl)acetonitrile
