Studies directed toward the synthesis of chiral tungsten and molybdenum carbonyl complexes

A major challenge that must be met for an asymmetric intermolecular Pauson–Khand reaction is to be able to limit the possible positions on the metal complex for the organic partners. Toward this end, the synthesis of monometallic systems derived from M(CO)6 and two bidentate ligands, in which the number of possible coordination sites is reduced to two, has been investigated.
