Research
Photoredox Catalysis
Photoredox catalysis enables mild, selective, and efficient organic transformations through visible light and a photoredox catalyst. It has become a powerful tool for C-C bond formation, C-H functionalization, and cross-coupling reactions, among others, making it a valuable technique in modern synthetic chemistry.
Ring-Strain Release
The presence of ring strain can greatly enhance the reactivity of chemical reactions by relieving the strain, thereby facilitating the formation of various useful structures. As a result, ring strain serves as a potent driving force in organic synthesis, enabling the construction of numerous valuable scaffolds with ease.
Electro-Synthesis
Electrochemical organic synthesis uses electricity to drive reactions and offers advantages over traditional methods, including improved selectivity, milder reaction conditions, and reduced waste. It has potential for the synthesis of complex molecules, making it a promising tool in modern synthetic chemistry.
