Rh(l)-catalysed hydrocarbonylation of alkynes 1 in the presence of primary amines gives substituted 2-pyrrolidinones 3 in a one-pot procedure. Replacement of hydrogen by hydrosilanes via silylcarbonylation leads to 4-silylated 1-aza-1,3-butadienes 5. These azadienes are converted with dimethyl acety
