Efficient catalysis of ammonia borane dehydrogenation

J Am Chem Soc. 2006 Sep 20;128(37):12048-9. doi: 10.1021/ja062419g.

Abstract

In the presence of an iridium pincer complex, dehydrogenation of ammonia borane (H3NBH3) occurs rapidly at room temperature in tetrahydrofuran to generate 1.0 equivalent of H2 and [NH2BH2]5. A metal borohydride complex has been isolated as a dormant form of the catalyst which can be reactivated by reaction with H2.
