of the backbone compared with the similar but strictly fixed anthracene backbone. Electron density on the central rhodium atom was investigated by IR experiments and by DFT computations. NMR monitoring of the reaction of the hydrido-chloro complex with base followed by application of H2 showed the presence of what are likely to be the active 14e− species and the dihydride derivative. Especially, noteworthy
摘要 合成并充分表征了一系列具有新型烷基-芳基混合“7-6-7”环骨架的 Rh-PCP 钳形配合物 (iPrPCP)Rh(L)。通过单晶 X 射线衍射分析确定,氢化-氯和羰基物质中的 7-6-7 环骨架在固态下分别呈现顺式和反式构象。这表明与类似但严格固定的蒽骨架相比,骨架具有灵活性。通过红外实验和 DFT 计算研究了中心铑原子上的电子密度。对氢化氯络合物与碱的反应进行 NMR 监测,然后施加 H2,表明存在可能是活性 14e-物质和二氢化物衍生物。尤其,值得注意的是,与相应的铱配合物相比,前者相对稳定。[本文有补充材料。访问出版商的在线版 Phosphorus, Sulfer, and Silicon 获取以下免费补充文件:附加文本、表格和数字。] 图形摘要
