Pericyclic Reactions and Rearrangements In many graduate students of chemistry, the world of pericyclic reactions and rearrangements is an intimidating sphere. These reactions, ruled by intricate orbital interactions and symmetry rules, are very important for successful postgraduate studies (e. g. MSc) and competitive examinations like CSIR-NET. The book Pericyclic Reactions and Rearrangements by Sudhir Nama is aimed at providing a road map through this very confusing world of reactions and its applications to students who face both these challenging tests. The present review will suggest whether it has been successful in this regard.
Content And Approach for MSc and CSIR-NET preparation :
Woodward-Hoffmann rules: a pretty in-depth discussion of these basic rules (probably including elaborate mechanistic explanations as well as a lot of examples that illustrate the utility of these rules in predicting reaction stereochemistry and feasibility).
The Comprehensive Study of Conrotatory and Disrotatory Ring Openings and Closures: A review with special emphasis on the orbital symmetry considerations at the core of conrotatory and disrotatory rings.
Cycloadditions: very detailed chapter on a few different cycloadditions e. g. [4+2] (Diels-Alder), [2+2], etc. with emphasis on regio- and stereoselectivity. The book would most likely have a lot of examples which might be relevant to exams.
Sigmatropic Rearrangements: An systematic study of various forms of sigmatropic shifts ([1, 3], [1, 5], [3, 3] Claisen, etc. ) and their theoretical and stereochemical effects.
Cheletropic Reactions; These are less commonly tested, but probably also included in the analysis of pericyclic processes to provide a more complete picture.
Practice Problems : The inclusion of many practice problems that are replicated in format and difficulty of MSc and CSIR-NET questions helps in preparing efficiently for exam. Worked solutions are also compulsory to get familiar with the methodology of problem solving.
Strengths for Exam Preparation:
Targeted Content: The book caters to the specific requirements of MSc & CSIR-NET aspirants and thus the content is directly relevant to the exam pattern.
Problem-Solving Focus: The emphasis on practice problems and worked solutions is a big strength for students in helping them develop the problem-solving skills and self-confidence.
Concise and Focused: The book likely avoids unnecessary details, presenting the core concepts efficiently and effectively.
Exam - Oriented Approach : The structure and content of the book is probably designed to meet the specific requirements / format of the exam.
Overall :
Sudhir Nama's "Pericyclic Reactions and Rearrangements" may well prove to be a very useful textbook for MSc students as well as for CSIR-NET.
