研究室紹介
Professor Jin Uk Han's research lab specializes in transition-metal-catalyzed asymmetric synthesis, with a strong focus on palladium- and gold-catalyzed reactions for the efficient and enantioselective construction of chiral molecules. Key research directions include asymmetric hydrosilylation, cross-coupling reactions, and the development of novel chiral ligands—particularly planar chiral ferrocene-based phosphines—for high-precision catalysis. The lab also explores sustainable catalytic processes under mild conditions, such as aerobic oxidation and room-temperature reactions, aligning with green chemistry principles. Their work contributes significantly to the synthesis of complex chiral building blocks with applications in pharmaceuticals and fine chemicals.

The reaction of organotitanium reagents, methyltitanium triisopropoxide [MeTi(i-PrO)3] and phenyltitanium triisopropoxide [PhTi(i-PrO)3], with aryl triflates and halides proceeded in the presence of 1.0 mol% of palladium catalyst coordinated with (R*)-N,N-dimethyl-1-[(S*)-2-(diphenylphosphino)ferrocenyl]ethylamine [(R*)-(S*)-PPFA] in refluxing THF to give a quantitative yield of the corresponding cross-coupling products.
Bis{(Rp)-2-[(1S)-1-methoxyethyl]ferrocenyl}arylphosphines (S,Rp)-9 (aryl=4-MeOC6H4 (9a), Ph (9b), 4-CF3C6H4 (9c), 3,5-(CF3)2C6H3 (9d)), which contain two planar chiral ferrocenyl moieties, were prepared via (Rp)-1-bromo-2-[(1S)-1-methoxyethyl]ferrocene ((S,Rp)-8). Asymmetric hydrosilylation of linear 1,3-dienes such as deca-1,3-diene (10a) with trichlorosilane in the presence of a palladium catalyst coordinated with 9d gave allylic silanes of up to 93% ee.
In the context of the energy crisis and global climate deterioration, the sustainable development of clean energy will become a new direction for future energy development. Based on the development process of clean energy in China in the past ten years, this paper expounds on China’s clean energy policy and development plan. The development of hydropower, wind power, and solar power in China in recent years is analyzed. On this basis, the Grey Forecasting Model is used to forecast the developmen
Gold-catalyzed aerobic oxygenative cleavage of triple bonds that occurs under the ambient pressure of air and at room temperature is reported; radical inhibition tests suggest that oxygenation occurs via a gold-bound metalloradical intermediate.
