Certain ethylenes and heterocyclic compounds substituted with the 2,4-dinitrophenylthio- group were synthesised and tested for activity against Venturia inaequalis, Botrytis cinerea, Fusarium bulbigenum and Cercospora melonis. 1-Alkylthio-1-(2,4-dinitrophenylthio)-2-cyano-2-(ethoxycarbonyl or cyano) ethylenes in which the Ph-S bond is not shielded by the alkyl substituent from attack, perhaps by nucleophilic
合成了某些被 2,4-二硝基苯硫基取代的乙烯和杂环化合物,并测试了它们对葡萄孢菌、灰葡萄孢、镰刀菌和瓜尾孢的活性。1-烷硫基-1-(2,4-二硝基苯硫基)-2-氰基-2-(乙氧羰基或氰基)乙烯,其中Ph-S键不受烷基取代基的攻击,也许是亲核细胞成分,是发现对文丘里亚有活性。3,5-Di(methyl- orethyl-thio)-4-cyanisothiazoles 对文丘病也有活性。2-取代的-5-(2,4-二硝基苯硫基)-1,3,4-恶二唑没有或很低的杀真菌活性,并且测试了几种 2-(2,4-二硝基苯硫基)杂环化合物的 2-(2, 4-二硝基苯硫基)-苯并噻唑和-苯并恶唑对文丘病具有良好的活性。
