Synthesis of New Boron-Containing Ligands Based on the Nucleophilic Addition of 1,10-Phenanthroline-5-Amine to Nitrile Derivatives of [2-B10H9NCR]– (R = Me, Et, nPr)

A series of substituted derivatives of the closo-decaborate anion of 1,10-phenanthroline-5-amine has been prepared in this work. The structure of the products has been established by multinuclear NMR spectroscopy, ESI-mass spectrometry, and IR spectroscopy. The structure of compound (NBu4)[2-B10H9NHC(C2H5)HNC12H7N2] was established by single crystal X-ray analysis.
