Organic Chemistry Mechanism Challenge 1

The video tutorial explores a chemical reaction involving photochemistry and cycloaddition, leading to the formation of a transient four-membered ring. The reaction is initiated by light, causing π bonds to convert into Sigma bonds. The tutorial discusses the instability due to ring strain and the subsequent rearrangement to form a more stable eight-membered ring. The process involves sodium hydroxide, leading to the formation of an enolate, which eventually reforms the carbonyl group. The video concludes with a mechanism challenge, summarizing the key steps and transformations in the reaction.
