N-Borylated Hydroxylamines [B12H11NH2OH]-as a Novel Type of Substituted Derivative of thecloso-Dodecaborate Anion

Methods for the preparation of N-substituted hydroxylamine [B12H11NH2OH](-)have been developed and optimized. The possibility of using two synthetic methods has been shown: (i) based on the hydroxylation of the deprotonated amino-closo-dodecaborate and (ii) theipso-substitution of the iodonium substituent with free hydroxylamine. A theoretical study of the [B12H11NH2OH](-)anion has been carried out by quantum-chemical calculations in the framework of density functional theory in order to determine its main structural characteristics.
