Abstract

Thermal or photoinduced isomerization of diruthenium bridging bisborylene complexes [{Cp*(H)₂Ru}₂(μ-BAr)₂] (1a, Ar = Ph; 1b, Ar = 3,4,5-F₃C₆H₂) led to nido-ruthenacarboranes 2a and 2b with newly formed B–C and B–H bonds. The reaction mechanism was analyzed by deuterium-labeling experiments and density functional theory calculations. Additionally, 2-fold B–H coupling between borylene and two hydrido ligands of 1a can be achieved, assisted by Lewis base IPr₂Me₂ to generate a dinuclear bridging borylene complex [(Cp*Ru)₂(μ-H)₂(μ-BPh)] (3). Our results provide new reactivity patterns for borylene-based functionalizations.

双硼铱钌配合物的反应性：通过双硼烯配体偶联形成 B-C 和 B-H 键

热或光诱导的二钌桥双硼烷配合物[{Cp*(H)2Ru}2(μ-BAr)2]（1a，Ar = Ph；1b，Ar = 3,4,5-F3C6H2）的异构化导致了具有新形成的 B-C 和 B-H 键的硝基钌硼烷 2a 和 2b。通过氘标记实验和密度泛函理论计算分析了反应机理。此外，在路易斯碱 IPr2Me2 的帮助下，硼烯和 1a 的两个氢配体之间可以实现 2 倍 B-H 耦合，生成双核桥接硼烯配合物[(Cp*Ru)2(μ-H)2(μ-BPh)] (3)。我们的研究结果为基于硼烯的官能化提供了新的反应模式。
