Gas-phase reactions of tetraborane(10) with 1-en-3-ynes: syntheses of the parent tricarbahexaborane, nido-2,3,4-C₃B₃H₇, and its derivatives

Mark A. Fox, Robert Greatrex and Alireza Nikrahi

The gas-phase reaction at 70 °C between B₄H₁₀ and 2-methylbut-1-en-3-yne, H₂CMeCCH, gives the new tricarbahexaborane derivatives 2–4 and the tetracarbahexaborane 5 as the major volatile products in an overall yield of 18%; reactions with H₂CCHCCH and H₂CCHCCMe lead to the first syntheses of the parent tricarbahexaborane nido-2,3,4-C₃B₃H₇ 1.
