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.
