Title: | Bimetallic Ni(II) complex with carboxylate bridging for homogeneous hydrogenation of alkenes with NaBH4 | Authors: | Kani, İbrahim Ünver, Hakan |
Keywords: | Hydrogenation Nickel Bimetallic Alkene Sodium borohydrate |
Issue Date: | 2020 | Publisher: | Pergamon-Elsevier Science Ltd | Abstract: | In this study, we present the synthesis and full characterization of the dimer Ni(II) complex, [Ni-2(dpaa)(2)(bPY)(2)(SO4)(H2O)]CH3OH, (dpaa = diphenyl acetic acid, bpy = 2,2'-bipyridine) with an N2O4 donor set and its hydrogenation activity on linear and cyclic alkenes (1-octene, t-2-octene, 1-hexene, cyclohexene, cyclopentene, benzene and styrene) with NaBH4 as a hydrogen source. 1-Octene and 1-hexene were reduced to the corresponding alkanes as the major products (81.3 and 91.2%, respectively), and the substrate isomerized the terminal alkenes to a mixture of internal alkenes as minor products (1-4%) under the studied conditions (subs/cat/reduct. 100/1/1 in methanol, 40 degrees C, 6 h). To optimize the reaction conditions for the reduction of styrene to ethyl benzene in methanol, the effect of subs./NaBH4 ratio, solvent and temperature were also investigated. (C) 2020 Elsevier Ltd.
