通过α-萘乙酸和SOC l2在无水苯中反应制得α-萘乙酰氯,然后与硫氰酸钾反应生成α-萘乙酰基异硫氰酸酯,再与对氯苯甲酰肼进行加成反应,生成新型化合物N-萘乙酰基-N’-对氯苯甲酰氨基硫脲。用薄层色谱法跟踪最后一步反应,确定了反应时间。产物结构经1H NMR、IR和元素分析确定。生物活性实验结果表明目标产物对稻子根生长具有促进作用,对大肠杆菌和枯草杆菌无明显抑菌作用。 Α-Naphthylacetyl chloride is obtained by the reaction of α-naphthalene acetic acid and SOC l2 in anhydrous benzene, and then reacted with potassium thiocyanate to form α-naphthylacetyl isothiocyanate, followed by p-chlorobenzohydrazide Addition reaction, generating a new type of compound N-naphthoyl-N’-p-chlorobenzoylaminothiourea. The last reaction was followed by TLC and the reaction time was determined. The structure of the product was confirmed by 1H NMR, IR and elemental analysis. The results of biological activity show that the target product has a promoting effect on rice root growth and no obvious bacteriostasis on E. coli and Bacillus subtilis.
