Their corresponding half -sandwich ruthenium (Ru) complexes ( Ru 1a-b , Ru 2a-b and Ru 3 ) were then successfully generated. The structure of all synthesised compounds was comprehensively elucidated via 1 H and 13 C nuclear magnetic resonance (NMR), elemental analysis and Fourier -transform infrared spectroscopies. Notably, the structural configuration of Ru 3 was delineated via X-ray diffraction. The catalytic efficacy of the Ru complexes was systematically probed in two distinct reactions: 1) transfer hydrogenation (TH) of ketones using 2-propanol as the hydrogen source and 2) reduction of nitroarenes to anilines using sodium tetrahydridoborate as the reducing agent in ethanol, conducted at ambient temperature. Comparative analysis of catalytic yields of the Ru complexes ( Ru 1a-b , Ru 2a-b and Ru 3 ) in both reaction types revealed that Ru 3 delivered superior catalytic performance in both types of reactions. Furthermore, scrutiny of the 1 H NMR spectrum during the TH reaction revealed formation of Ru-hydride species.eninfo:eu-repo/semantics/closedAccessQuinoline/naphthalene derivativesRuthenium(II)-arene complexesTransfer hydrogenationReduction of nitroarenesArticle131210.1016/j.molstruc.2024.1384052-s2.0-85191885371Q1WOS:001237547300001Q2
