3,5-Dichloro-1,2,4-thiadiazole was allowed to react with different arylboronic acids under different Suzuki-Miyaura coupling conditions: at room temperature 5-aryl-3-chloro-1,2,4-thiadiazoles were obtained and at toluene reflux temperature the products were 3,5-diaryl-1,2,4-thiadiazoles. Sequential coupling reactions lead to 3,5-diaryl-1,2,4-thiadiazoles with non-identical aryl groups. The structure of 3-methoxy-5-(4-methoxyphenyl)-1,2,4-thiadiazole was established from X-ray crystallographic data.

3,5-二氯-1,2,4-噻二唑的铃木-宫浦偶联反应。

在不同的 Suzuki-Miyaura 偶联条件下,使 3,5-二氯-1,2,4-噻二唑与不同的芳基硼酸反应:在室温下得到 5-芳基-3-氯-1,2,4-噻二唑和在甲苯回流温度下,产物是3,5-二芳基-1,2,4-噻二唑。连续偶联反应产生具有不同芳基的 3,5-二芳基-1,2,4-噻二唑。3-甲氧基-5-(4-甲氧基苯基)-1,2,4-噻二唑的结构由X-射线晶体学数据确定。
