RT journal article T1 Multiple metal-bound oligomers from Ir-catalysed dehydropolymerisation of H3B$NH3 as probed by experiment and computation A1 Kumar, Amit A1 C. Johnson, Heather A1 N. Hooper, Thomas A1 S. Weller, Andrew A1 García Algarra, Andrés A1 A. Macgregor, Stuart A2 Ciencia de los Materiales e Ingeniería Metalúrgica y Química Inorgánica AB Multiple metal-bound oligomers in the dehydropolymerisation of H3B$NH3 have been observed by electrospray-ionisation mass spectrometry and NMR spectroscopy using the catalytic metal fragment {Ir(PCy3)2(H)2}+. A computational study suggests that sterics dictate whether multiple dehydrogenation/ B–N coupling of amine-boranes H3B$NRR'H (R, R0 ¼ Me or H) is observed, and also demonstrates the experimentally observed requirement for additional amine-borane to promote dehydrocoupling.
