Pericyclic Reactions: Theory, Mechanisms, and Prediction

Predicting the outcome of advanced organic reactions often requires understanding the underlying electronic structure and symmetry. This course provides a clear, step-by-step introduction to pericyclic reactions, equipping you with the theoretical tools to analyze reaction feasibility and stereochemistry, from cycloadditions to photochemistry. By mastering the foundational concepts, you will gain the ability to rationalize why certain reactions occur under thermal versus photochemical conditions. What you'll learn: * Understand the fundamental principles of orbital symmetry and the Woodward-Hoffmann rules. * Master the mechanisms and stereochemical outcomes of electrocyclic reactions and cycloadditions. * Apply Frontier Molecular Orbital (FMO) theory to rationalize thermal and photochemical reaction pathways. * Analyze complex sigmatropic rearrangements and cheletropic reactions. * Learn the specific photochemistry mechanisms involving carbonyl compounds and common sensitizers. * Practice applying theoretical principles to predict transition states and reaction feasibility. The material starts with foundational orbital theory and symmetry concepts, progresses through the major classes of pericyclic reactions, and concludes with advanced topics like photochemical transformations. This course is designed for students and professionals new to advanced mechanistic organic chemistry who want a strong theoretical foundation. No prior experience with pericyclic reactions is required, only basic organic chemistry knowledge. Begin your journey into the world of predictable organic synthesis today.
