Due to the widespread demand for more efficient photocatalytic approaches\, constant innovation is require d to reach the desired reactivity\, selectivity\, and stability\, while ma king these methods sustainable and accessible. For this reason\, during th e last decade\, the Li lab has reported numerous tools that provide soluti ons to existing challenges on diverse fronts\, including but not limited t o: the development of new reagents to access facile and streamlined functi onalization reactions\, the in-depth study of new catalytic pathways for t he exploration of diversified reactivities\, and the design of new and acc essible devices that allow for accelerated optimization of reaction condit ions.\n\nIn this talk\, we will focus on the area of homogeneous photocata lysis\, identifying areas of opportunity\, and current efforts to address these challenges while providing standardized solutions. Some of the publi shed works to discuss during the talk will provide insight into first\, de veloping a series of bench-stable photocleavable reagents for the perfluor oalkylation of electron-rich aromatics under metal-free and redox- and pH- neutral conditions. Second\, the stepwise discovery of simple triarylamine s as catalytic electron donors in Electron Donor-Acceptor (EDA) complexes. And finally\, the design of a 3D-printed photoreactor compatible with Hig h-Throughput Experimentation (HTE) for the discovery and optimization of n ovel reactions promoted by visible light.\n\nBio:\n\nDurbis J. Castillo Pa zos did his bachelor’s degree in chemistry at the Autonomous University of the State of Mexico. As an undergrad he had the opportunity to participat e in several internships across Europe and North America\, where he gained experience in nanotechnology\, peptide synthesis\, structural biology\, a nd computational chemistry. After finishing his degree in 2017\, Durbis sp ent one year working as a consultant for the National Autonomous Universit y of Mexico using QSAR for regulatory affairs.\n\nIn 2018\, Durbis started his doctoral studies at Â鶹´«Ã½ÍøÕ¾ under the supervision of Prof. Chao-Jun Li\, working in the development of novel synthetic methodologies mediated by light\, being funded through the Vanier\, CONACYT\, and Tomlin son scholarships. During his PhD\, he secured an internship at the pharmac eutical company Merck\, where he gained expertise in DNA-Encoded Libraries (DEL). After defending his thesis in the Fall of 2024\, he joined Merck a s a Senior Scientist in the Discovery Chemistry department\, where he curr ently works at the High-Throughput Experimentation group to accelerate the impactful discovery of new medicines and treatments.\n DTSTART:20260120T180000Z DTEND:20260120T193000Z LOCATION:OM 10\, Maass Chemistry Building\, CA\, QC\, Montreal\, H3A 0B8\, 801 rue Sherbrooke Ouest SUMMARY:Â鶹´«Ã½ÍøÕ¾ Chemical Society Seminar Series- (Winkler Lecture) Durbis J.
