Organic Photochemistry and Pericyclic Reactions: A Foundation

Organic chemistry can be complex, but understanding reactions driven by light or concerted electron movement is crucial for advanced synthesis and mechanistic study. This course provides a clear, foundational pathway into these essential reaction types. By the end of this course, you will possess a solid grasp of the underlying principles of photochemistry and the theoretical framework of pericyclic reactions, enabling you to analyze complex synthetic pathways and interpret reaction mechanisms with confidence. What you'll learn: * Understand the electronic excitation processes in organic molecules, including singlet and triplet states and the Jablonski diagram. * Apply the Woodward-Hoffmann rules and Frontier Molecular Orbital (FMO) theory to predict pericyclic reaction stereochemistry. * Analyze the mechanisms of key photochemical reactions, such as Norrish Type I/II cleavage, Paterno-Büchi, and photoisomerization. * Practice interpreting reaction diagrams and transition states for electrocyclic, cycloaddition, and sigmatropic rearrangements. * Master the selection rules that govern thermal and photochemical reactivity in concerted bond-forming processes. * Learn fundamental concepts of computational chemistry used to model and verify complex reaction pathways and transition state energies. The course begins with core principles of molecular orbital theory and light absorption, progressing through detailed mechanisms of photochemical and thermal pericyclic reactions. You will practice applying theoretical rules to predict the outcome and stereochemistry of challenging synthetic problems. This course is designed for chemistry students and professionals new to advanced organic synthesis. No prior experience with photochemistry or advanced physical organic chemistry is required.
