Organometallic chemistry is now firmly entrenched in the methodology of organic synthesis. That this is so has been clearly demonstrated during the course of this meeting. Two themes have emerged. First, the power of organometallic reagents to provide enhanced selectivity in stoichiometric processes. In this area the use of carbene complexes, transition metal acyls, 7t-allyIs and arenes are already offering powerful new methods for the synthesis of a wide range of functionalized compounds with very high diastereo- and enantioselectivities. Many of the methods described are already efficient and routine. Intramolecular cycloadditions of eneynes, catalysed by palladium, now represent short routes to polycyclic systems of some complexity. Even in the held of selective protection organometallics offer advantages, for example in the case of reactive acetylenes.
