Project Details

Description

Cataytic carbonylation is an important reaction because it allows the synthesis of high added value products(aldehydes, esters, carboxylic acids, etc.) from simple substrates, such as olefins and alcohols, by means of the direct addition of carbon monoxide. Appropriate combinations of metals and ligands catalyze this addition. The proposal involves the synthesisi of new ligands to be applied in catalytic carbonylation processes, namely hydroformylation, hydrocarboxylation, hydroesterification, and carbonylation of alcohols and halogenated aromatic heterocycles. The new ligands are chiral disphosphines and diphosphites designed to promote the activity and to control the regio-and stereoselectivity of the rhodium and palladium catalysts, which will be used in these reactions. The project involves the synthesis and characterization of ligands and the corresponding rhodium and palladium complexes, followed by preliminary catalytic assays with standard substrates for each reaction. The reaction will be also applied to other substrates of synthetic interest, such as terpenes, pyrimidines and propenyl and allylaromatics of natural origin (eugenol, isoeugenol, safrol, etc...) Furthermore, spectrocopic and kinetic studies, including isotopic labeling, will be carried out in order to gain insight on the mechanism of these reactions. This should allow a better design of new catalytic systems
