New Methods for Preparation of the Monofluorosubstituted Derivative of the closo-Borate Anion [2-B10H9F]2–, Its Properties, and Analysis of Its Reactivity

Abstract New methods for the preparation of a monofluoro-substituted derivative closo -decaborate anion [2-B 10 H 9 F] 2– have been developed. Various synthetic strategies used, where Bu 4 NF, Me KF/18-crown-6, and NH HF 2 act as sources F – anion. A feature proposed is absence fluorinating agent in reaction mixture. In course work, optimal conditions synthesis determined products characterized. Using theoretical modeling methods, main indices reactivity monofluorinated derivatives calculated. The influence solvation effects on nucleophilicity target objects has studied. structure obtained compounds confirmed by 1 H, 11 B, 19 NMR spectroscopy, ESI mass spectroscopy.
