The first successful Pd/C-mediated Sonogashira coupling of iodothiophene with terminal alkynes in water is described here. Pd/C-CuI-PPh(3) was found to be an efficient catalyst system for this coupling reaction. Using this economic and reliable process a variety of acetylenic thiophenes with a wide range of functional groups were prepared in good yields. Synthetic applications and in vitro anticancer
此处描述了碘噻吩与末端炔烃在水中首次成功的Pd / C介导的Sonogashira偶联。发现Pd / C-CuI-PPh(3)是该偶联反应的有效催化剂体系。使用这种经济可靠的方法,可以以高收率制备各种具有广泛官能团的炔属噻吩。描述了某些合成化合物的合成应用和体外抗癌性能。
