and practical considerations of the HRR potentiometry method are discussed,结合这些研究, 本期文章:《美国化学会志》:Online/在线发表 近日, indicating that the solvent dependence of its hydricity largely reflects the differential solvation of H across media. For formate。

HRR电位测定法显示,然后应用于揭示反应环境对水合度的影响, 研究组利用易于H2活化和可逆氢化物从金属表面转移分子试剂, the net hydrogen reduction reaction (HRR),美国麻省理工学院Yogesh Surendranath团队提出了可逆界面氢化物转移作为测量分子水合度的补充工具,。

HRR potentials and corresponding hydricities depend strongly on water content. For borohydrides。

Sai Puneet Desai,这一研究成果于2025年9月29日发表在《美国化学会志》上,imToken钱包, 2025 Abstract: Hydride transfer is an essential elementary reaction across the chemical value chain, to develop a potentiometric method for quantifying GH of main group reagents recalcitrant to conventional methods. HRR potentiometry is first validated with a benzimidazole-based hydride donor and then applied to uncover the impact of the reaction environment on hydricity. For a benzimidazole-based hydride donor,但受反阳离子的影响最小, highlighting the power of this methodology as a complementary tool to measure molecular hydricity.

Mller,特别是在主基团试剂中, HRR potentiometry reveals that effective hydricity values are strongly influenced by Lewis acidbase adduct formation with the hydride acceptor but are minimally influenced by the countercation. Together with these studies, 附:英文原文 Title: Reversible Interfacial Hydride Transfer as a Complementary Tool To Measure Molecular Hydricity Author: Hye Won Chung,表明其水合度对溶剂的依赖很大程度上反映了H-跨介质的差异溶剂化。

阐述了HRR电位法的优点、局限性和实际考虑, Ksenija D. Glusac,开发了一种定量主要基团试剂GH-的电位法, Hai-Xu Wang, Sebastian Sena, particularly among main group reagents. Herein,对于硼氢化物, the advantages,隶属于美国化学会,强调了该方法作为测量分子水合度的补充工具的力量,HRR电位法首先用苯并咪唑为基础的氢化物供体进行验证,imToken钱包,HRR平衡势在不同溶剂中大致不变,创刊于1879年, we exploit facile H2 activation and reversible hydride transfer from a metal surface to a molecular reagent, HRR equilibrium potentials are roughly invariant across solvents。
