Аннотация:CAN-catalyzed reactions between a-ferrocenyl ethanol or ferrocenyl methanol and S-, N- and O-carborane
nucleophiles are reported. This approach is an efficient and simple procedure for the preparation
of carborane derivatives containing ferrocenyl units. Energy and geometry optimizations of some carboranylthio-,
carboranylamino- and carboranyloxy-substituted ferrocenes have been calculated using the
density functional theory. A series of new ferrocene-containing carborane 1,2,3-triazoles have been synthesized
in good yields through a facile copper-mediated 1,3-dipolar cycloaddition reactions of alkynyl
ferrocenes with [(o-carboran-1-yl)methyl]azide. Molecular structure of carborane-substituted ferrocenyl
triazole was established by single crystal X-ray diffraction study. Representative examples of all ferrocenyl
carboranes prepared were characterized by IR, 1H and 11B NMR spectroscopy.
