Gold Complexes And Novel Caffeine Derivatives
Item
- Description
- The range of applications for gold complexes is rapidly growing since they have potential uses in chemical and biological sensing, electronics, and the pharmaceutical industry. This project involves the preparation of complexes of gold derived from caffeine, a well-known stimulant that is commercially available. Interestingly, the molecular structure of caffeine includes an imidazole ring and, as such, it is susceptible to chemical transformations, including the formation of carbene derivatives. More specifically, methylation of the unsubstituted nitrogen on caffeine forms an N-heterocyclic carbene (NHC) precursor, which was converted to the corresponding thione and selone derivatives. These monodentate ligands have been coordinated to gold(I) halides, and these results will be described in detail in this report. These gold complexes serve as molecular models for the binding of thiones and selones to gold surfaces.
