Reactivity of Diruthenium Bisborylene Complexes: Formation of B–C and B–H Bonds via Borylene Ligand Coupling
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.
