Abstract Palladium complexes of N -acylbenzotriazole derivative ligands were synthesized and characterized. The catalytic activities of complexes of ([PdL1(OAc) 2 ] and [PdL2(OAc) 2 ]) were investigated in relation to hydrogenation reactions of styrene, 1-octene and cyclohexene in [bmim][BF 4 ] 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 [PdL1(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.
