Reactions of these salts with silver(I) oxide in methanol led to dinuclear N-heterocyclic carbene silver complexes (3a-3c). All of the compounds were characterized by 1H NMR, 13C NMR and elemental analyses. Molecular weights of the silver complexes were confirmed by MALDI-TOF mass spectrometry. Preliminary catalytic studies using all the silver complexes were performed on three-component coupling reaction of p-formaldehyde, piperidine and phenylacetylene. Complexes 3a and 3c exhibited good catalytic activities under neat conditions. The silver complexes showed luminescence properties in CH3CN at room temperature. © 2018 Elsevier B.V.EnglishCatalyst activityLuminescenceMass spectrometryOrganic compoundsSaltsSilverSilver oxidesCoupling reactionDibenzimidazolium saltLuminescence propertiesMALDI-TOF mass spectrometryN-heterocyclic carbenesPhenylacetylenesSilver complexesThree-component coupling reactionSynthesis (chemical)Dinuclear N-heterocyclic carbene silver complexes: Synthesis, luminescence and catalytic studiesArticle10.1016/j.molstruc.2018.11.053
