A series of BNHC Ag(I) halide complexes were synthesized and their structures have been elucidated through the use of multinuclear NMR and FT-IR spectroscopy. Furthermore, the pseudo-linear geometry of two different compounds was substantiated by single-crystal X-ray diffraction. Silver-based A3-coupling was achieved for both acyclic and cyclic secondary amines using a diverse set of alkynes to afford propargyl amines with yields of up to 95 %. The present approach is environmentally benign and water is generated as the sole byproduct.eninfo:eu-repo/semantics/closedAccessN -Heterocyclic carbeneSilver complexesA3-couplingPropargyl amineDesign of efficient benzimidazole-derived N- heterocyclic carbene Ag(I) catalysts for aldehyde -amine -alkyne couplingArticle131810.1016/j.molstruc.2024.1392392-s2.0-85198026743Q2WOS:001269206000001N/A
