Influence of the presence of heteroatoms in the olefin chain on the Pauson–Khand reaction with metal (Cr, W) carbene enyne complexes

The study of the influence caused by the presence of an heteroatom, either at an internal or terminal site of the olefin, on the outcome of the Pauson–Khand cycloaddition in metal carbene enyne complexes is reported. In this study the steric and electronic effects have been evaluated. A diversion fr...

Summary:The study of the influence caused by the presence of an heteroatom, either at an internal or terminal site of the olefin, on the outcome of the Pauson–Khand cycloaddition in metal carbene enyne complexes is reported. In this study the steric and electronic effects have been evaluated. A diversion from the normal course of the reaction mechanism is observed.
