A new concise synthesis route of 2-phenylbenzo[b]thiophen-3(2H)-one 1,1-dioxide from benzo[b]thiophen-3(2H)-one 1,1-dioxide was developed using palladium-catalyzed C(sp3)-H arylation. Compared with the traditional route, this protocol can effectively save many steps and combine with the current research hotspot, C(sp3)-H activation. Moreover, this catalytic system is easy to operate and a good yield
使用钯催化的 C,从苯并[b]噻吩-3(2H)-酮 1,1-二氧化物合成 2-苯基苯并[b]噻吩-3(2H)-酮 1,1-二氧化物的新路线(sp3)-H 芳基化。与传统路线相比,该协议可以有效地节省许多步骤,并结合当前的研究热点,C(sp3)-H 激活。此外,该催化体系易于操作并且可以实现良好的收率。
