A series of hetero-biscarbene silver(I) and gold(I) complexes the general formula [NHC-M-MIC]PF6 (NHC=imidazol-2-ylidene, MIC=1,2,3-triazol-5-ylidene) have been prepared via treatment NHC-M-Cl precursors in reaction with an situ generated mesoionic carbene (MIC). The new heteroleptic fully characterized including NMR spectroscopy, elemental analysis, melting points single crystal X-ray diffraction. derivatives were employed successfully solvent free KA2 (ketone-alkyne-amine) coupling for preparation a quaternary carbon-containing propargyl amines while, biscarbenes, demonstrated good performance A3 (aldehyde, amine, alkyne) benzylic oxidation processes under low catalyst loadings.
