Nucleophilic Addition of Polyfunctional Amines to Acetonitrile Derivatives of closo-Borate Anions [BnHn – 1NCCH3]– (n = 10, 12)

Methods for the preparation of new amidine-closo-borates based on the processes of nucleophilic addition of bifunctional amines containing free functional groups –NH2, –SH to nitrile derivatives of the closo-decaborate and closo-dodecaborate anions have been developed. These derivatives can potentially act as agents for 10B-NCT and serve as starting compounds for further preparation of borylated derivatives by organic chemistry methods. The structures of the obtained compounds have been confirmed by 1H, 11B, 13C NMR spectroscopies and ESI mass spectroscopy.
