Conclusions
-
1.
The integral intensity of the C-H stretching vibration band was measured in the spectra of more than 50 substituted o-carboranes.
-
2.
The induction mechanism was confirmed for the transmission of the effect of the substituent X in the system\(\begin{array}{*{20}c} X & H \\ \backslash & / \\ C & { - C} \\ \backslash & / \\ {B_{10} } & {H_{10} } \\ \end{array} \) on the C-H bond. The mechanism for the transmission of the effect is more complicated in the case where the substituent is attached to the B atom in the 3 position of the carborane ring.
