摘要

The heteroborate stanna-closo-dodecaborate shows double substitution in the reaction with alkylated acetonitrile. The reaction product, the charge compensated E,E-isomer, was isomerized into the Z,Z-isomer and hydrogenated at the double bonds. Furthermore the methylated cluster shows less reactivity and the monosubstituted cluster was isolated. The reaction products were characterized by elemental analysis and NMR spectroscopy. Three of the substitution products were also characterized by single crystal structure analysis.
