The Synthesis and Insecticidal Activity of a Series of 2‐Aryl‐1,2,3‐triazoles
摘要:
Two synthetic routes to 2-aryl-1,2,3-triazoles are outlined. These have been used to synthesise a wide range of compounds of this structural type. Their insecticidal activities were evaluated against a number of veterinary and public health pests. The activity of these compounds is especially good against the housefly (Musca domestica). Structure-activity relationships are discussed particularly in relation to the physical properties of the compounds.
摘要 基质分离技术已用于研究分子氟 F 2 与几种烷基硫化物以及三甲基膦反应的初始中间产物。虽然之前对这些碱与 ClF 和 Cl 2 反应的研究表明形成了电荷转移复合物,但这里没有证据表明复合物形成。所研究的每个系统都会发生相当直接的反应,在几种情况下会导致氢置换产物,而在其他系统中,光谱证据支持直接加成反应。例如,在 F 2 /H 2 S 系统中,假设最初形成 H 2 SF 2,然后在汞弧辐照下消除 HF 以形成 HSF。
