Here, we demonstrate palladium-catalyzed Hiyama-type cross-coupling reactions of aryl thianthrenium or phenoxathiinium salts. By employing stable and inexpensive organosilanes, the arylation, alkenylation, and alkynylation were realized in high efficiency using commercially available Pd(tBu3P)2 as the catalyst, thus providing a reliable method for preparation of biaryls, styrenes, and aryl acetylenes
在这里,我们演示了芳基噻啉鎓盐或吩恶噻鎓盐的钯催化桧山型交叉偶联反应。通过使用稳定且廉价的有机硅烷,以市售Pd( t Bu 3 P) 2为催化剂,高效地实现了芳基化、烯基化和炔基化,从而为制备联芳基、苯乙烯和芳基乙炔提供了可靠的方法。在温和条件下具有广泛的官能团耐受性。鉴于以显着的区域选择性方式从简单芳烃中获得芳基噻啉盐或吩噻噻啉盐,该方案还为复杂生物活性支架的后期修饰提供了一种有吸引力的方法。
