第一篇:An enantioselective, intermolecular dehydrogenative Heck arylation of trisubstituted alkenes to construct remote quaternary stereocenters has been developed. Using a new chiral pyridine oxazoline ligand, good to high enantioselectivity is achieved for various combinations of indole derivatives and trisubstituted alkenes. However, some combinations of substrates led to lower enantioselectivity, which provided the impetus to use structure enantioselectivity correlations to design a better performing ligand.
第二篇:We have developed an efficient strategy for the production of stable β-palladium hydride (PdH0.43) nanocrystals with controllable shapes and remarkable stability. The as-synthesized PdH0.43 nanocrystals showed impressive stability in air at room temperature for over 10 months, which has enabled the investigation of their catalytic property for the first time. The prepared PdH0.43 nanocrystals served as highly efficient catalysts in the oxidation of methanol, showing higher activity than their Pd counterparts. These studies opened a door for further exploration of β-palladium hydride-based nanomaterials as a new class of promising catalytic materials and beyond.

我们开发了一种用来生产具有可控形貌和i良好稳定性的pdH0.43纳米晶的有效方法。原位合成的pdH0.43纳米晶表现出非常好的稳定性,室温下可在空气中放置十个月以上,这使它们的催化性能得以首次研究。在甲醇的氧化反应中,pdH0.43纳米晶作为高效催化剂比pd纳米晶表现出更高的活性。该项研究为进一步探索β-palladium hydride(β-氰化钯?)系列纳米晶作为一种前景可观的催化材料奠定了基础。     第二篇   外行  请多指教
