Liye Chen
Liye grew up in Dalian, China. He completed his undergraduate study in Tsinghua University. After spending one year as a research assistant in Shanghai Institute of Organic Chemistry, Liye moved to Princeton University in 2013, where he worked for Prof. Brad Carrow on catalyst design that utilizes important but hitherto under investigated noncovalent interactions. During that time, he developed tri(1-adamantayl)phosphine, a long-sought-after compound, that imparts exceptional stability to low-coordinate otherwise short-lived metal complexes and excels in challenging cross-coupling reactions. In 2018, Liye joined the Hartwig group as a postdoctoral researcher. He is now working on the synthesis of polar-functionalized polyolefins by direct C-H functionalization.
