title: Progress in carbonylative [2+2+1] cycloaddition: utilization of a nitrile group as the π component.
abstract: New tricks, old reactions: The treatment of 2-(1,2-propadienyl)phenylacetonitrile derivatives with a catalytic amount of [{RhCl(CO)dppp}2 ] (dppp=1,3-bis(diphenylphosphanyl)propane) under a CO atmosphere produced benzo[f]oxyindole derivatives. This aza-Pauson-Khand-type reaction was applicable to aliphatic substrates, thus resulting in the formation of the azabicyclo[3.3.0]octadienone derivatives.
