Abstract
The dodecamethyl closo-borane dianion [closo-B (CH ) ] and anion [closo-B (CH ) ] were synthesized and characterized. Dodecamethyl-closo dodecaborate (2−) was produced from [closo-B H ] , using trimethylaluminum, and methyl iodide and modified Friedel-Crafts reaction conditions. The anion was produced from the dianion by chemical oxidation using ceric (4) ammonium nitrate in acetonitrile. The anion and dianion were both characterized by H and B NMR spectroscopy, high-resolution fast atom bombardment (FAB) mass spectrometry, cyclic voltammetry, and single-crystal X-ray diffraction. The “camouflaged” polyhedral borane anion [closo-B (CH ) ] , can be used as a precursor to materials that offer a broad spectrum of novel applications ranging from drug applications and supramolecular chemistry to use as a weakly-coordinating dianion.
