However, 1m and 1n under the same conditions gave N-coordinated Ru(II) complex (3). The structures of the compounds were elucidated by NMR, FT-IR, UV–Vis, HR-MS spectroscopic methods and elemental analysis. In addition, the structures of 2k and 3 were studied by X-ray crystallography. The electrochemical properties of the complexes were investigated. Ru(II)-NSHC complexes have been used as catalysts in the transfer hydrogenation of carbonyls to secondary alcohols in the presence i-PrOH/KOH. Additionally, the effects of structural differences arising from different alkyl groups on the nitrogen atom in the benzothiazole skeleton in Ru(II)-NSHC complexes on anticancer, antifungal and antimicrobial activity were also examined. © 2024 Elsevier B.V.eninfo:eu-repo/semantics/closedAccessAnticancerBenzothiazol-2-ylideneBiological activityHalf-sandwich Ru(II) complexN-heterocyclic carbeneTransfer hydrogenationArticle131810.1016/j.molstruc.2024.1394242-s2.0-85199436326Q2
