摘要
6-Ethyl-1,2,3,4,5-pentamethyl-2,3,4,5-tetracarba-nido-hexaborane(6), 1,2,3,4-tetraethyl-5,6,7,8-tetracarba-nido-octaborane(8), its bis-Fe(CO)(3) complex, and decaalkyl-2,6,8,10-tetracarba-nido-decaboranes(10) were characterized by multinuclear magnetic resonance methods (B-11, C-13 NMR spectroscopy, and heteronuclear C-13{B-11} decoupling experiments). Particular attention was given to measure spin-spin coupling constants J(C-13, B-11). These and other NMR parameters were compared with calculated data, based on optimized gas phase geometries on the B3LYP/6-311 + G(d, p) level of theory, and reasonable agreement was found.
