Using a recently discovered precatalyst, the first Pd-catalyzed Suzuki–Miyaura reactions using aryl sulfamates that occur at room temperature are reported. In complementary work, it is demonstrated that a related precatalyst can facilitate the coupling of aryl silanolates, which are less toxic and reactive nucleophiles than boronic acids with aryl chlorides. By combining our results using modern electrophiles
使用最近发现的预催化剂,首次报道了在室温下发生的使用芳基氨基磺酸盐的钯催化铃木-宫浦反应。在补充工作中,证明相关的预催化剂可以促进芳基硅烷醇盐的偶联,芳基硅烷醇盐比硼酸与芳基氯的毒性和反应性亲核试剂更低。通过结合我们使用现代亲电子试剂和亲核试剂的结果,报道了第一个使用芳基氨基磺酸盐的桧山-丹麦反应。
