Abstract
The process of rearrangement of the octadecahydroeicosaborate anion [trans-B20H18]2– → [iso-B20H18]2– in organic solvents (acetonitrile, DMF, DMSO) under UV irradiation has been studied using 11B NMR spectroscopy in dynamics. It has been shown that the time of complete isomeric transition depends on the solvent used. In acetonitrile, complete conversion of the [trans-B20H18]2– anion to the iso form is achieved in 1 h; in DMF, the process takes about 2 h; in DMSO, it takes about 3 h. The reverse process of rearrangement of the macropolyhedral borohydride anion [iso-B20H18]2– → [trans-B20H18]2– has been studied under the influence of temperature in DMF; it has been shown that an increase in the reaction time and temperature of the reaction solution is accompanied by degradation of the boron cluster.
