Interests
Inorganic and Organometallic Chemistry
We are currently interested in using doubly linked cyclopentadienyl ligands to hold two metal centers next to each other. The resulting dinuclear complexes will be tested as catalysts for small molecule activation and functionalization.
The preferred metal is ruthenium with rhodium and iridium making occasional guest appearances. We have been able to prepare a series of ruthenium complexes as shown below.
The
reaction was initially performed in the converted domestic microwave oven
connected to a pressure transducer and control system to prevent
overpressurization of the reaction vessel. Crude but effective.
We
have now gone big city and the reaction is now performed in a CEM Discover
microwave, shown on the right. A huge
step up in performace.
Reaction
with LiAlH4 yields the corresponding bisdienyl complex.
Protonation with HOTf yields the hexakisacetonitrile complex.
