New Pd complexes for adipic acid synthesis through the alkoxycarbonylation of butadiene


Adipic acid is considered as the most important dicarboxylic acid of global market. Its main application concerns the synthesis of polyamides-6,6, also called “Nylon”. Today, this chemical is obtained via a petrochemical process starting from cyclohexane oxidation. Therefore, there is a high interest in the development of new environmentally friendly synthetic pathways allowing us to prepare adipic acid starting from renewable sources, while keeping high values of productivity and avoiding the formation of pollutant side-products.
An interesting route for the preparation of adipic acid from renewable sources implies the utilization of butadiene, which can be directly obtained from bioethanol (which in turn is produced through sugars fermentation), as platform molecule. The corresponding adipate is prepared through the alkoxycarbonylation of butadiene in the presence of CO and an alcohol. This reaction can be considered as fully « sustainable », as CO can also be obtained from CO2 through the “reverse water-gas shift” reaction. 
The present PhD aims to prepare new ligands and their corresponding organometallic complexes for their use as catalysts in the alkoxycarbonylation of butadiene. In addition, mechanistic studies at both theoretical at experimental level will be performed.

Keywords: Organometallic synthesis, coordination chemistry, homogeneous catalysis, NMR, DFT.
