Abstract
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 om the normal course of the reaction mechanism is observed. (C) 1999 Elsevi er Science S.A. All rights reserved.
