Dehydrocoupling of dimethylamine-borane promoted by manganese(II) m-terphenyl complexesTools Sharpe, Helen R., Geer, Ana M., Blundell, Toby J., Hastings, Fiona R., Fay, Michael W., Rance, Graham A., Lewis, William, Blake, Alexander J. and Kays, Deborah L. (2017) Dehydrocoupling of dimethylamine-borane promoted by manganese(II) m-terphenyl complexes. Catalysis Science and Technology, 8 (1). pp. 229-235. ISSN 2044-4753 Full text not available from this repository.AbstractTwo- and three-coordinate manganese m-terphenyl complexes are precatalysts for the dehydrogenation of dimethylamine-borane (Me2NH·BH3) affording one equivalent of molecular hydrogen and half an equivalent of [Me2N–BH2]2. Experimental studies into the nature of the catalyst indicate that small changes in the coordination environment give rise to significant differences in the reaction mechanism, occurring through a homogeneous mechanism for two-coordinate precatalysts, whilst for the three-coordinate species a heterogeneous mechanism takes place where nanoparticles are responsible for the catalysis.
