Abstract

Quaternisation of methylimidazole by bromoalkanes afforded imidazolium salts (1) which were converted to Ag-NHC complexes bearing imidazol-2-ylidenes, [(C-n mim) Ag-2](2)[Ag2Br4], 2, using the silver oxide. The catalytic activities of silver-N-heterocyclic carbene (NHC) complexes were investigated in the three component coupling reaction of aldehyde, alkyne and amine to propargylamines.
