摘要: 本文合成一系列新的1-氰乙酰基-4-取代芳酰基硫脲化合物(Ⅰ),研究了(Ⅰ)在碱催化条件下环化为1,2,4-三唑类衍生物的反应。初步鉴定了(Ⅰ)类化合物对小麦等植物生长性能的促进作用。

Abstract: In this paper a series of new 1-cyanoacetyl-4-aryl thiosemicarbazides (Ⅰ) have been synthesized. When aroylisothiocyanate reacted with 1-cyanoacetylhydra-zine in acetonitrile or acetone, the corresponding compound (Ⅰ) was formed respectively in yield of about 50-95%. Promoting effects of compounds (Ⅰ) on growth of plant have been tested preliminary.Compounds (Ⅰ) may be cyclized in the presence of 2N K2CO3aqueous solution to give 1,2,4-friazoline-5-thione derivatives (Ⅱ) in fairly good yield (70-90%).
