Pericyclic and Photochemical Reactions

Pericyclic reactions involve the almost simultaneous reorganization of bonding electron pairs through a cyclic transition state that enables products to be formed directly without the formation of an intermediate. In this series, we feature the following pericyclic reactions:

• Eschenmoser-Claisen rearrangement
• Mislow-Evans rearrangement
• Overman rearrangement

Other named reactions of the pericyclic reactions include:

A photochemical reaction occurs when a chemical absorbs energy in the form of light and is transformed into another product. A common example of a photochemical process is plant photosynthesis. Featured in this series are:

• Nazarov cyclization
• Paterno-Buchi reaction

Other named photochemical reactions are:
