Key texts in the renowned Oxford Chemistry Primers series have been fully refreshed and updated to suit the needs of today's students, lecturers, and postgraduate researchers. The rigorous and yet accessible treatment of each subject area is ideal for those wanting to know more about a particular topic not covered comprehensively in existing undergraduate texts. Moreover, cutting-edge examples and applications throughout the texts show the relevance of thechemistry being described to the real world. Pericyclic reactions constitute a fundamental class of organic chemistry, including such commercially important synthetic reactions as theDiels-Alder reaction. This primer gives a concise and accessible account of these reactions, enabling students to recognise the different types of pericyclic reaction and understand their application in organic synthesis.
