Abstract

The synthesis of new 3-halogeno nido derivatives of o-carborane, [3-X-7-R-7,8-nido-C₂B₉H₁₀]^- (X = Br, I; R = H, CH₃, C₆H₅) is described, through deboronation of the compounds 3-X-1-R-1,2-closo-C₂B₁₀H₁₀, previously synthesised in our laboratory. These nido products have been fully characterised using ¹H-, ¹¹B- and ¹³C-NMR spectroscopies, MALDI-TOF and, for [3-1-7,8-nido-C₂B₉H₁₁]^- by an X-ray crystallographic study. The influences of the halogen moiety on both the B(3) resonance and that of the bridge proton are discussed. © 2002 Elsevier Science B.V. All rights reserved.
