Reaction of the [B10H11]– Anion with Dicyanostilbenes

Abstract

In this work, the interaction of the closo-decaborate anion with a series of substituted dicyanostilbenes was studied. A range of new derivatives of the composition [B₁₀H₉R]^–, where R is a phenanthrenedicyan substituent with substituents at positions 1 and 10, was obtained. Optimal reaction conditions were selected. To increase the stability of the target compounds, amidine derivatives were synthesized by reacting the obtained nitrile derivatives of the closo-decaborate anion with ammonia in an aqueous-alcoholic medium. The composition and structure of the obtained compounds were determined using multinuclear NMR spectroscopy, mass spectrometry, and IR spectroscopy.
