Cleavage of the cyclic substituent in the [B10H9O2C4H8]−, [B10H9OC4H8]−, and [B10H9OC5H10]− anions upon the interaction with negatively charged N-nucleophiles

The interaction of the [B10H9O2C4H8]−, [B10H9OC4H8]−, and [B10H9OC5H10]− anions with negatively charged N-nucleophiles has been studied. It has been shown that such reactions yield doubly charged substituted closo-decaborates with a nitrogen-containing group attached to the cluster through an alkoxyl spacer. Compounds with pendant NO2−, N3−, N(CO)2C6H4−, and NHC6H5 groups have been synthesized.
