Abstract We report here the synthesis, structure, and reactions of the oxygen and hydrogen doubly bridged polyhedral borane anion [{mu}-B{sub 20}H{sub 17}-OH]{sup 2-} (4). A demonstration of the facile alkylation of 4 is provided by heating the {mu}-B{sub 20}H{sub 17}2{sup 3-} ion with ethyl iodide in MeCN to produce 3 ([{mu}-B{sub 20}H{sub 17}OC{sub 2}H{sub 5}]{sup 2-}) in 88% yield. The efficacious alkylation reaction of this oxygen-bridged polyhedral borane anion provides a route to oxygen-substituted species. The derivatization of 4 with organic substrates will lead to a variety of derivatives having potential utility in BNCT. We are continuing the exploration of this novel chemistry. 15 refs., 1 fig.
