The palladium-catalyzed coupling reaction of 3-thiomethyl-1,2,4-triazine 1 with different organoboron compounds in the presence of copper(I) 3-methylsalicylate proceeds to afford the corresponding 3-substituted-1,2,4-triazines in good yield. This approach leads very easily to a large range of C-5 and C-6 unsubstituted as-triazines.
在铜(I) 3-甲基水杨酸盐的存在下,钯催化的3-硫甲基-1,2,4-三嗪1与不同的有机硼化合物的偶联反应顺利进行,获得相应的3-取代-1,2,4-三嗪,产率良好。这种方法非常容易得到多种C-5和C-6未取代的三嗪类化合物。
