Transition-metal-catalyzed carbon-carbon bond formation reactions provide the most basic technical support for the synthesis of natural products, research and development of medicines and pesticides, modification and improvement of functional materials. Phenolic derivatives are widely existed in nature and have gradually become excellent substitutes for aryl halides. Alkenes and alkynes are often involved synthon in organic synthesis and also abundant petroleum hydrocarbon compounds. The combination of activation of inert aryl carbon-oxygen bonds with conversion of alkenes and alkynes through transition-metal-catalyzed process has high value for organic synthesis. This project aims to establish a Nickel-catalyzed system for hydroarylation of alkene and alkyne through carbon-oxygen bond activation, followed by the optimization of reaction conditions and exploration of substrate scope. This reaction could construct carbon-carbon bonds with phenol derivatives and alkenes or alkynes. In this project, we will control the regioselectivity as well as stereochemical selectivity by using ligand effect, solvent effect and other factors, and many kinds of framework structure of products could be obtained. The modification of complex molecules containing aryl carbon-oxygen bonds or alkenyl groups and alkyne groups will be carried out and the chemical selectivity of this reaction will also be studied which could display the application of this reaction in complex systems. By using experimental methods of physical organic chemistry and density functional theory calculations, this project will elucidate some catalytic issues such as reaction mechanism, rate determining step and catalytic cycle.
