Development of Re and Ir Complexes as Catalysts for Oxygen Atom Transfer and C-H Activation/Functionalization
Abstract:

The development of homogeneous catalysts for the efficient utilization of our chemical feedstocks will be described. Specifically, we will discuss our efforts at synthesizing novel oxorhenium catalysts for the conversion of syngas to high value chemicals. The discovery of a new mechanism for the activation of CO by transition metal oxos will be discussed.

In addition we will discuss our efforts at developing new catalysts for the catalytic functionalization of C-H bonds. This work is in conjunction with the Center for Enabling New Technologies through Catalysis (CENTC). We will describe new insights into the activation of C-H bonds by Cp*Ir(NHC) complexes (NHC = N-Heterocyclic carbene) as a function of the solvent used for H/D exchange reactions of benzene and a variety of deuterium sources. We will also describe a new catalytic method for the functionalization of benzoic acids to produce benzo[c]chromen-6-ones.
