Thermal‐or SiO2‐induced reactions of the Michael adducts of 1, 2‐aromatic dinucleophiles
and alkynylchromium (0) carbene complexes, compounds 7–10, form different products in …

Four types of N-heterocyclic ring systems were successfully constructed from the reactions of
1-alkynyl Fischer carbene complexes (OC) 5M C (OEt) C⋮ CPh (1)(M= Cr, W) and …

The study of the scope of the Pauson− Khand reaction on alkynyl (allylamino) carbene
pentacarbonyl complexes of chromium and tungsten (0) is reported. This reaction affords …

The addition of different nucleophilic compounds (aliphatic and aromatic alcohols, thiols and
phosphines) to alkynylalkoxycarbene complexes has been studied. The reaction with …
