Abstract
This thesis mainly focuses on the catalytic carbon-carbon bond formation using gold catalysts. The thesis is divided into two areas: The first area investigated using gold, silver complex to catalyze the cyclization of propargyl alcohol molecules to produced the cyclohexanone products in high yield at room temperature. The other area investigates the catalytic cyclization of cis-2,4-dien-1-al using the same gold catalysts ; this cyclization can selectively produce the cyclopentenol product. In our previous study, we using Platinum or Palladium as catalysts, 2-cyclopentenone or 4-alkylidene-3,4-dihydro-2H-pyran will be formed as products.
