Abstract

The processes of nucleophilic addition of acetylacetone as a C-nucleophile to multiple bonds of nitrile derivatives of boron cluster anions have been studied in this work. The structures of the products have been established by multinuclear NMR spectroscopy, ESI-mass spectrometry, and IR spectroscopy. The structure of compound (NBu₄)[2-B₁₀H₉NH=C(C₂H₅)C(C(OH)CH₃)C(O)CH₃] has been established by single crystal X-ray analysis.
