stabilised by P. a. kurdica gum were employed as a heterogeneous catalyst in Mizoroki–Heck and Suzuki–Miyaura cross‐coupling reactions at low palladium loading (0.1 mol%) under aerobic, phosphine‐free and ligand‐free conditions in water. Product yields of up to 98%, a facile work‐up, no evidence of leached palladium from the catalyst surface and smooth recovery of the catalyst, which can be reused at least
对于支撑在钯纳米(PD-NPS)的合成的单釜法绿色黄连木大西洋kurdica(P。一个。kurdica)胶进行说明。该天然树胶用作还原剂和稳定剂。Pd-NPs / P的形成。一个。使用诸如傅里叶变换红外光谱,紫外可见分光光度法,扫描和透射电子显微镜,X射线衍射,能量色散X射线光谱法,动态光散射和波长色散X射线等多种技术验证了库尔迪卡胶催化剂光谱学。由P稳定的Pd-NPs 。一个。kurdica胶是在用作非均相催化剂Mizoroki-的Heck和Suzuki-Miyaura交叉耦合在水中需氧,游离膦和无配体的条件下具有低钯负载(0.1摩尔%)的反应。产品收率高达98%,操作简便,没有证据表明钯从催化剂表面浸出,并且催化剂的回收率平稳(可重复使用至少八次),证实了所研究反应中催化剂的效率。版权所有©2015 John Wiley&Sons,Ltd.
