| Popis: | The nucleophilic addition of the monocarbonyl derivative of the closo-dodecaborate anion [B12H11CO]– with N- and O-nucleophiles has been studied. This process proceeds under mild conditions in high yield. Not only primary and secondary amines but also tertiary ones can be added. The resulting borylated derivatives are thermally unstable, and the C–O and C–N bonds split upon heating forming the initial [B12H11CO]– anion. In an acidic medium in aqueous solutions, borylated derivatives hydrolize forming the carboxylate derivative of general formula [B12H11COOH]–. |
