Abstract

Ammonia Borane (AB), NH3BH3, is currently being examined as a material for the storage and distribution of hydrogen as an alternative to hydrocarbon fuels. The direct regeneration of dehydrogenated AB from dihydrogen is thermodynamically unfavorable and an economical method for the regeneration of AB remains a challenge. The complex [Rh(dmpe)2](CF3SO3) activates H2 and in the presence of a base, generates a strong hydride donor, HRh(dmpe)2. Our studies investigate the formation of B-H bonds via hydride transfer reactions from HRh(dmpe)2 to boron containing substrates. Experimental data support theoretical calculations that predict the hydride affinity of a variety of boron compounds. These combined initial studies are part of a novel regeneration scheme that couples spent AB fuel digestion with reduction of boron via the catalytic activation of dihydrogen.
