Abstract: y Deboration of 1-PhCH2-1,2-C2B10H11 by heating in ethanolic potassium hydroxide afforded Me4N+ [7-PhCH2-7,8-C2B9H11](-) which was treated with excess halosuccinimide (NCS, NBS) in acetonitrile or with elemental iodine or bromine in methanol to obtain Me4N+ [7-PhCH2-9,11-X-2-7,8-C2B9H9](-) (X = Cl, Br, I). The reaction of 1-PhCH2-1,2-C2B10H11 with an equimolar amount of iodine gave a mixture of Me4N+center dot[7-PhCH2-11-I-7,8-C2B9H10](-) and Me4N+[7-C6H5CH2-9-I-7,8-C2B9H10](-) at a ratio 1 : 1.8 due to steric effect of the benzyl substituent. The B-11 chemical shifts of each mu-H tautomer of Me4N+ [7-PhCH2-9,11-X-2-7,8-C2B9H9](-)(X = H, F, Cl, Br, I) were calculated at the DFT level of theory, and their contributions to the average B-11 NMR spectrum and the corresponding tautomeric equilibrium constants were determined.
