Synthesis of di-gold(I) metallotweezer

Abstract

The aims of this current project in my passage through the Organometallic Chemistry group and Homogeneous Catalysis research group, at the University Jaume I, were divided in the following three:  To obtain the 2,6-Bis(3-ethynyl-5-tert-butylphenyl)pyridine, a ligand precursor for the preparation of a new di-Au(I) metallotweezer. This compound is reported in the literature, but we aim to improve its synthesis.  To synthetize the new metallotweezer based of the alkynyl fragment in 2,6-Bis(3- ethynyl-5-tert-butylphenyl)pyridine, in combination with a N-heterocyclic carbene ligand fused with a pyrene fragment.  To study this system for the recognition of organic substrates by exploiting the - surface areas of the polyaromatic-adorned NHCs ligands.
