Abstract
Abstract This thesis is devided into two sections. The first topic is chiral gold(I)-catalyzed [3+2] cycloaddition between ethyl diazoacetates, nitrosoarenes, and vinyldiazo carbonyls to yield chiral isoxazolidine products. The second one explores the synthesis of a novel of precursors and the growth tungsten oxide film by atomic layer deposition using that were just produced. Chapter 1 Chiral gold(I)-catalyzed cycloaddition of ethyl diazoacetate, nitrosoarenes, and vinyldiazo carbonyl to yield isoxazolidine derivatives stereoselectively, are already described. We try to raise the enantiomeric excess (ee%) of the products by using bulky substrate. Chapter 2 As for Chapter 2, with the wide application of atomic layer deposition technology, we aim to generate atomic layer deposition tungsten oxide films using tungsten hexacarbonyl as the basic substrate. We synthesized tungsten complexes to increase the reactivity and the thermal stability by the meditation of different ligands. We choose the best precursor to do atomic layer deposition and generate tungsten oxide films successfully.
