Abstract
A series of hetero-biscarbene silver(I) and gold(I) complexes of the general formula [NHC-M-MIC]PF6 (NHC=imidazol-2-ylidene, MIC=1,2,3-triazol-5-ylidene) have been prepared via the treatment of NHC-M-Cl precursors in reaction with an in situ generated mesoionic carbene (MIC). The new heteroleptic complexes have been fully characterized including NMR spectroscopy, elemental analysis, melting points and single crystal X-ray diffraction. The silver(I) derivatives were employed successfully in the solvent free KA2 (ketone-alkyne-amine) coupling for the preparation of a series of quaternary carbon-containing propargyl amines while, the gold(I) biscarbenes, demonstrated a good performance in the A3 (aldehyde, amine, alkyne) coupling and the benzylic oxidation processes under low catalyst loadings.
期刊介绍:
ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
