School of Science Department of Chemistry 4 Borane Functionalization via Boryl Radical Supervisor: QUAN Yangjian / CHEM Student: FU Yiyi / CHEM XU Yinghe / CHEM Course: UROP 1100, Fall UROP 1100, Fall A radical process of β-addition of borane to “polarized” alkyne by visible light irradiation is reported. The selectivity control of E (trans)/Z (cis) isomers and their interconversions are still under investigation. The current optimal conditions provide a E/Z ratio of 85/15. During the substrate scope investigation, a group of alkynes with electron-withdrawing groups (EWD), such as ester or amide, are synthesized through Sonogashira coupling or other condensation processes. Herein, we present a progress report of substrate synthesis. The substrates will be transformed to the hydroboration products after further condition screening. Borane Functionalization via Boryl Radical Supervisor: QUAN Yangjian / CHEM Student: GAO Bin / CHEM Course: UROP 1100, Fall Despite the well-established practice of remote functionalization catalyzed by transition metals, research on metal-free systems remains relatively unexplored. Recently, Prof. Quan’s lab developed a method for the remote functionalization via boron catalysis instead of transition metal ones. This innovative method has several advantages over previous techniques such as the absence of metal and good functional group tolerance, showing its potential in the synthesis field. In this report, relevant academic studies will be discussed. Additionally, I would summarize the practical skills gained from conducting experiments such as the synthesis of substrates, the remote functionalization, and the diversification of products. Design, Synthesis, and Applications of New Metal-Organic Frameworks Supervisor: QUAN, Yangjian / CHEM Student: CHAN Fung / CHEM Course: UROP 1100, Fall Through this project I have learnt various reaction related to Metal-Organic Framework and usually play a role as a photocatalyst. Moreover, I have also learnt the proper separation approach to separate the metalorganic framework from the reaction mixture and carry out characterization.
