碩士 === 國立中興大學 === 化學系所 === 105 === In the first part of this thesis, we report an efficient palladium-catalyzed ortho-C-H arylation of acetophenone oxime Ethers with aryl pinacol boronic esters, leading to the biaryl derivatives in good yields. The sequential process of iridium-catalyzed C-H borylation and palladium-catalyzed ortho-C-H arylation makes the present protocol access functionalized biaryl arenes. In the second part of this thesis, we achieve a simple and elegant method for dithioacetalization of aldehyde using blue LEDs irradiation under photochemical reaction. The salient features of this method are broad substrate scope, good tolerance of electron donating and withdrawing group, and metal free and solvent free conditions. It is noteworthy that our present protocol is eco-friendly in nature and we will develop LEDs-promoted reaction in future green chemistry avenues.
