C-C键的形成反应是有机化学中最重要的基本反应.本文发展了一种简单、有效钯催化的α-溴代二硫缩烯酮与芳基硼酸的Suzuki-Miyaura偶联反应.该反应的实现,不仅建立了一种简单、有效合成α-芳基-α-烯酰基二硫缩烯酮化合物新方法,而且扩展了α-溴代二硫缩烯酮类化合物在有机合成中的进一步应用. The formation reaction of CC bonds is the most important basic reaction in organic chemistry.In this paper, a simple and effective palladium-catalyzed Suzuki-Miyaura coupling reaction of α-bromothioketal ketene and arylboronic acid was developed. , Not only a simple and effective new method for synthesizing α-aryl-α-alkenoyl dithiane ketones has been established, but also the further application of α-bromo-dithiane ketones in organic synthesis has been expanded .
