Lecture Room 3
We have been able to reduce dinitrogen selectively and catalytically to ammonia at 1 atm and room temperature with protons and electrons. Reduction takes place at a single molybdenum center that is sterically protected against bimetallic decomposition reactions with meta-terphenyl-substituted triamidoamine ligands such as [(HIPTNCH2CH2)3N]3- where HIPT is hexaisopropyl-metaterphenyl. The reducing equivalents make either ammonia (~60% from dinitrogen) or dihydrogen. All evidence suggests that N2 is being reduced at a single Mo center in which the oxidation state of the metal varies between Mo(III) and Mo(VI).
Recent studies concern complexes that contain a variety of "Hybrid" ligands, in which only two HIPT groups are present in the ligand, with the third group being a sterically less demanding aryl. Attempts to reduce dinitrogen catalytically led to little or no ammonia being formed from dinitrogen. [(HIPTNCH2CH2)3N]3- complexes of tungsten, chromium, and vanadium all failed to yield any catalytic turnover of dinitrogen to ammonia. Other ligand variations will be discussed as time permits.
Richard R. Schrock received his Ph.D. degree in inorganic chemistry from Harvard in 1971 under John Osborn. After one year as an NSF postdoctoral fellow at Cambridge University working for Lord Jack Lewis, and three years in Central Research and Development at DuPont in Wilmington Delaware, he moved to M.I.T. in 1975. He became full professor in 1980 and the Frederick G. Keyes Professor of Chemistry in 1989. His interests include the inorganic and organometallic chemistry of high oxidation state, early metal complexes, the chemistry of high oxidation state dinitrogen and related complexes, the controlled polymerization of olefins and acetylenes with alkylidene complexes, and the catalytic reduction of dinitrogen. He has received numerous awards including: ACS Cope Scholar Award (2001), the RSC Centenary Medal (1991), the Sir Geoffrey Wilkinson Medal (2002), the Sir Edward Frankland Prize (2004), the August Wilhelm von Hofmann Medal of the German Chemical Society (2005, with R. H. Grubbs), and the ACS F. Albert Cotton Award in Synthetic Inorganic Chemistry (2006). In 2005 he shared the Nobel Prize in Chemistry with R. H. Grubbs and Y. Chauvin. He has been elected to the American Academy of Arts and Sciences and the National Academy of Sciences. He was Associate Editor of Organometallics for eight years, has published more than 460 research papers, and has supervised over 140 Ph.D. students and postdocs.
