pushing all fluorines toward the other face. The reaction also pushed fluorine toward the same face as nitrogen and oxygen in heterocycles such as indole and benzofuran. Science, this issue p. 908 Rhodium catalysis in a nonpolar solvent produces cyclic fluorocarbons with all the fluorines on the same face of the ring. All-cis-multifluorinated cycloalkanes exhibit intriguing electronic properties. In particular

hydrogenation of halogenatedquinolines. Highly dispersed Pd in the Au matrix of bimetallic catalysts with low Pd content triggers hydrogen activation on Pd sites and leads to the selective adsorption of halogenatedquinolines on Au sites in the tilted orientation. The generated active hydrogen species can diffuse from Pd to Au sites for the hydrogenation of the tilted halogenatedquinolines, resulting in
卤代喹啉的催化加氢是长期的挑战,这是由于苛刻的反应条件和由于脱卤而产生的幻灭性的化学选择性。探索新型催化材料仍然是一个巨大的挑战。在此,密度泛函理论计算表明,卤化喹啉通过倾斜方向上的氮原子选择性地吸附在Au表面上,而通过平取向的喹啉环上选择性地吸附在Pd上。在倾斜方向上,C–Cl键远离催化剂表面,这可以避免表面活化的氢物种对C–Cl键的氢化。一系列Au 1- x Pd x双金属催化剂沉积在CeO 2上纳米棒通过简便的化学沉积方法制成。具有低Pd含量的Au 1- x Pd x催化剂可提高活性,并提高卤代喹啉加氢的化学选择性。Pd含量低的双金属催化剂的Au基质中Pd的高度分散会触发Pd位点上的氢活化,并导致卤化喹啉在倾斜方向上选择性吸附在Au位点上。生成的活性氢物质可以从Pd扩散到Au位置,以进行倾斜卤代喹啉的氢化反应,从而抑制了脱卤作用,并对预期产物具有较高的化学选择性。
