Abstract

The nucleophilic substitution of the reactive chlorine atoms of the n-butylboron-capped hexachlorine-containing clathrochelate precursor with the thiol-terminated closo-decaborate (PPh4)2[B10H9OCH2CH2OCH2CH2SH] in the presence of triethylamine afforded the closo-decaborate-containing clathrochelate dodecaanion [Fe{[(B10H9OCH2CH2OCH2CH2S)2Gm]3-(BBun)2}]12−, which was isolated in the form of its tetraphenylphosphonium and sodium salts. The complexes obtained were characterized using elemental analysis, UV-VIS, 1H, 11B, and 13C{1H} NMR, and IR spectroscopies.
