(2013). Catalytic amine-borane dehydrogenation by a PCP-pincer palladium complex: A combined experimental and DFT analysis of the reaction mechanism. Dalton Transactions, 42, 3533-3541.1477-9226https://hdl.handle.net/11441/70449Catalytic dehydrogenation of ammonia-borane (NH3·BH 3, AB) and dimethylamine borane (NHMe2·BH 3, DMAB) by the PdII complex [(tBuPCP)Pd(H 2O)]PF6 [tBuPCP = 2,6-C6H 3(CH2PtBu2)2] leads to oligomerization and formation of spent fuels of general formula cyclo-[BH 2-NR2]n (n = 2,3; R = H, Me) as reaction byproducts, while one equivalent of H2 is released per amine-borane equivalent. The processes were followed through multinuclear (31P, 1H, 11B) variable temperature NMR spectroscopy; kinetic measurements on the hydrogen production rate and the relative rate constants were also carried out. One non-hydridic intermediate could be detected at low temperature, whose chemical nature was explored through a DFT modeling of the reaction mechanism, at the M06//6-31+G(d,p) computational level. The computational output was of help to propose a reliable mechanistic picture of the process.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1039/c2dt32273k
