Zhou, Xiaoguang;Malakar, Santanu;Dugan, Thomas;Wang, Kun;Sattler, Aaron;Marler, David O.;Emge, Thomas J.;Krogh-Jespersen, Karsten;Goldman, Alan S. research published 《 Alkane Dehydrogenation Catalyzed by a Fluorinated Phebox Iridium Complex》, the research content is summarized as follows. The authors report an Ir acetate complex with a fluorinated Phebox ligand (2,6-bis(4,4-dimethyl-4,5-dihydrooxazol-2-yl)-3,5-bis(trifluoromethyl)phenyl) that is a highly effective catalyst for acceptorless dehydrogenation of alkanes. Under typical acceptorless dehydrogenation conditions, a high turnover frequency was obtained, which is limited by the rate of expulsion of H2 from the reaction solution Rates and turnover numbers for acceptorless dehydrogenation are significantly greater than found for the nonfluorinated analog. As in the case of the nonfluorinated analog, Na+ acts as a cocatalyst with the fluorinated catalyst again yielding greater rates and total turnovers. Computational studies shed light on the possible mechanistic pathways. The initial alkane activation is a net Ir-H/C-H bond metathesis giving an Ir-alkyl bond and loss of H2; this is the slowest chem. step in the cycle. The lowest-energy pathway is calculated to proceed via concerted metalated deprotonation (CMD) of the alkane. Pathways proceeding via transition states with oxidative addition (Ir(V)) character, however, are only slightly higher in energy. These transition states can lead either to Ir(V) intermediates, which then lose H2, or connect directly to a dihydrogen complex. The role of Na+ is largely to promote dechelation by coordinating to an acetate O, opening a vacant coordination site that allows reaction with the alkane. This coordination by Na+ prevents the CMD mechanism from operating, but it significantly lowers the energy of the Ir(V) TSs. NBO anal. shows a net transfer of charge from the alkane atoms to the metal complex in the Ir(V) TSs, with and without coordinated Na+. Thus, the oxidative addition is actually reductive in nature, driven in part by electrophilicity of the metal center. The Na+ cation further increases electrophilicity in addition to promoting dechelation. The greater activity of the fluorinated catalyst compared with the parent complex can also be explained in terms of the electrophilic nature of the reaction. The fluorinated catalyst is also more resistant to decomposition than the nonfluorinated analog.
