Dr. Bernardeta C. Parkin, BSc PhD (Imperial) CChem MRSC : has been a lecturer in Inorganic Chemistry at Queen Mary, University of London since 1995.
One of the most important applications of organometallic compounds is their ability to act as catalysts for a wide variety of organic transformations. In recent years, development of asymmetric catalysts has become increasingly important, as such organometallic species not only accelerate the reaction of associated substrates but also differentiate diastereomeric transition states to control product stereochemistry. The chemistry of early transition metal mediated organic transformations, particularly the area of asymmetric synthesis, has focussed on derivatives of group (IV) transition metals, with very little data on the reactivity of molybdenum and tungsten compounds. With the exception of ring opening metathesis polymerisation (ROMP) and epoxidation of alkenes by peroxo species, very few group (VI) systems have found widespread catalytic applications.
Current research in progress has centred on the synthesis of chiral ligands (particularly diolates) and high oxidation state complexes of molybdenum and tungsten. These complexes are being developed as potential catalysts for C-C bond forming reactions (eg. Alkylation of aldehydes, Aldol condensation, Diels Alder reaction).
