Pericyclic Reactions and Organic Photochemistry. Instructor: Prof. S. Sankararaman, Department of Chemistry, IIT Madras. The aim of the course is to make students familiar with the concepts and applications in two important topics in advanced organic chemistry, namely concerted organic reactions and organic photochemistry. Pericyclic reactions are concerted organic reactions and are governed by Woodward-Hoffmann rules. Different methods of analysis of pericyclic reactions to arrive at the Woodward-Hoffmann rules will be presented. Synthetic applications and mechanisms of various pericyclic reactions will be discussed. Similarly the concepts involved in understanding organic photochemical reactions, their mechanisms and applications in organic synthesis will be presented. This course will uncover all the major topics in pericyclic reactions and organic photochemistry. In addition to lectures there will be tutorial sessions and assignments in this course.
