Conclusions
-
1.
A series of C-functional derivatives of (3)-1,2-dicarbaundecaborate was synthesized and some of their properties were studied.
-
2.
Apparent ionization constants of acids of the (3)-1,2-dicarbaundecaborate series were measured and it was found that they are very weak carboxylic acids.
-
3.
Upon reaction with excess LiA1H4, under mild conditions the carbonyl,\(\begin{array}{*{20}c} \backslash \\ {CH(OH)} \\ / \\ \end{array}\), and CH2OH groups of dicarbaundecaborate ketones and alcohols are reduced to CH2 and CH3 groups, respectively.
-
4.
The effect of Grignard reagent on ketones and esters of the dicarbaundecarbprate series was studied and it was established that the composition of reaction products depends both on the steric hindrance of the carbonyl group and on the electron-donating effect of the (3)-1,2-dicarbaundecaborate substituent.
