Synthesis and ligand substitution in polyhedral borane anions and transition metal complexes of heteroatom borane cages

everal new metallaheteroboranes have been synthesized, including one new complex of the dicarbollide nido-7,8-;The palladium-mediated substitution reaction was extended to icosahedral metallaheteroboranes. Treatment of 1,1-(;Using this substitution method, a metallaborane complex containing palladium (III) and the first doubly charge-compensated ollide ion, 1,2-Br;A potentially general method to substitute neutral for hydride ligands on borane anions, resulting in charge-compensated boranes, is demonstrated. This method uses a palladium reagent,...
