The goals of this research program are to elucidate the mechanisms of           metal-catalyzed atom transfer reactions.  The general approach is to            characterize reactive intermediates in proposed catalytic cycles and            to isolate the elementary steps in catalysis.  Reaction                         stereoelectronics and ligand design are used to explore strategies to           impose selectivity on these catalytic reactions.  Specific goals for            the next grant period are:  (1) to continue the elaboration of the              chemistry of peroxometal and oxometal complexes; (2) to design and              prepare catalysts for site-selective, shape-selective and                       enantioselective molecular recognition and catalytic oxygenation; and           (3) to extend the metal nitride and metal imide chemistry which was             developed in the previous grant period toward catalysts which activate          and transfer nitrogen.                                                                                                                                          Most reactions of other substances with oxygen from the atmosphere are          catalyzed by metal ions, present either as constituents of proteins or          as trace constituents of water solutions.  Better understanding of the          mechanisms of metal-catalyzed oxidation reactions is important both             for the development of more efficient catalysts for industrial                  utilization of oxygen and for a deeper understanding of how some                important enzymes work.  During the previous grant period this                  research group has synthesized catalysts which are very efficient in            causing some organic chemicals to react with oxygen in such a way that          only one of several possible products are formed, as well as metal-             containing compounds which are models of some enzymes that catalyze             biological oxidations.
