  To offset the environmental impact of platinum‐group element (PGE) mining, recycling techniques are being explored. Porous organic polymers (POPs) have shown significant promise owing to their selectivity and ability to withstand harsh conditions. A series of pyridine‐based POP nanotraps, POP‐Py, POP‐pNH2‐Py, and POP‐oNH2‐Py, have been designed and systematically explored for the capture of palladium

  为了抵消铂族元素（PGE）开采对环境的影响，正在探索回收技术。多孔有机聚合物（POPs）由于其选择性和承受苛刻条件的能力而显示出巨大的前景。已经设计并系统地探索了一系列基于吡啶的POP纳米捕集阱，POP-Py，POP- p NH 2 -Py和POP- o NH 2 -Py，以捕获钯（最常用的PGE之一）。所有的POP纳米捕集阱均显示出记录的吸收和快速捕获，其中的氨基对提高性能至关重要。在POP nanotrap再生和选择性进一步测试发现，POP- ö NH 2 -py跑赢POP-p NH 2 -Py。单晶X-射线分析表明，POP- ö NH 2 -py提供更强的复合物相比，POP- p NH 2 -py由于氨基和协调的氯分子之间的分子内氢键。这些结果证明了对吸附剂的轻微修饰如何可以最大化其性能。

• Mechanistic Studies on the Pd-Catalyzed Vinylation of Aryl Halides with Vinylalkoxysilanes in Water: The Effect of the Solvent and NaOH Promoter

  The mechanism of the Pd-catalyzed vinylation of aryl halides with vinylalkoxysilanes in water has been studied using different catalytic precursors. The NaOH promoter converts the initial vinylalkoxysilane into a highly reactive water-soluble vinylsilanolate species. Similarly, deuterium-labeling experiments have shown that, irrespective of the catalytic precursor used, vinylation occurs exclusively at the CH vinylic functionality via a Heck reaction and not at the C-Si bond via a Hiyama cross-coupling. The involvement of a Heck mechanism is interpreted in terms of the reduced nucleophilicity of the base in water, which disfavors the transmetalation step. The Heck product (beta-silylvinylarene) undergoes partial desilylation, with formation of a vinylarene, by three different routes: (a) hydrolytic desilylation by the aqueous solvent (only at high temperature); (b) transmetalation of the silyl olefin on the PdH Heck intermediate followed by reductive elimination of vinylarene; (c) reinsertion of the silyl olefin into the PdH bond of the Heck intermediate followed by beta-Si syn-elimination. Both the Hiyama and Heck catalytic cycles and desilylation mechanisms b and c have been computationally evaluated for the [Pd(en)Cl-2] precursor in water as solvent. The calculated Gibbs energy barriers support the reinsertion route proposed on the basis of the experimental results.
