In this lesson, we introduce the concept of electrocyclic reactions and how they can be effected thermally or photochemically. We take an indepth look at two prototypical reactions involving hexatriene and cyclobutene and their respective mechanisms and stereochemistry. In particular, we study the conrotatory and disrotatory mechanisms that are described by the WoodwardHoffmann rules and how they determine the stereochemistry of the products.
