Palladium complexes of N-acylbenzotriazole derivative ligands were synthesized and characterized. The catalytic activities of complexes of ([PdLl (OAc)(2)] and [PdL2(OAc)(2)]) were investigated in relation to hydrogenation reactions of styrene, 1-octene and cyclohexene in [bmim][BF4] as greener reaction media 100% ethyl benzene conversion was obtained with both complexes in 1 h reaction time. Additionally, 100% 1-octene conversion was reached within the same period of time with [PdL2(OAc)(2)] complex. In cyclohexene hydrogenation, product formation reached up to 67% at 363 K with [PdLl (OAc)(2)] complex. Reusability tests were conducted under the highest product conversion conditions, and both catalysts were found to be efficient up to 5 cycles for all substrates. The other reaction parameters such as solvent effect, H-2 (g) pressure, n(s)/n(c) ratio were also investigated. (C) 2017 Elsevier B.V. All rights reserved.
