Synthesis and Characterization of Oxonium Functionalized Rhenium Metallaborane


The synthesis, characterization, and reaction mechanism of a series of oxonium derivatives of the rhenium containing metalladecaborane [nido-6-Re(CO)3B9H13][NMe4] are reported herein. The oxonium species were synthesized using tetrahydrofuran, 1,4-dioxane, and diethyl ether. The crystal structure of the tetrahydrofuran derivative [2-(CH2)4O-nido-6-Re(CO)3B9H12] was determined and compared to the isostructural manganese compound. The title compound crystallizes in the Triclinic space group P-1 with (a = 7.0835(5) Å, b = 9.6971(6) Å, c = 12.5762(8) Å, α = 73.5750(10)º, β = 75.5520(10)º, γ = 87.061(2)º, volume = 802.22(9), Z = 2). This facile functionalization strategy will facilitate future investigations of rhenium containing metallaboranes and metallacarboranes.
