Claisen Study guides, Class notes & Summaries

preparation of anhydride and mechanism ,pure and impure concept, claisen ester condensation and mixed claisen ester condensation and dieckmann's condensation

This document covers the first half of Chapter 17: Reactions at the alpha-Carbon of Carbonyl Compounds, Enols and Enolates, and alpha-beta Unsaturated Carbonyl Compounds. These notes were taken from lecture and start from a description of the reactivity of such compounds and certain reaction that coincide with them.

Learn Organic Chemistry in depth with written examples, arrow pushing mechanisms, and notes. It covers aldol, Michael, amines, cross-coupling, reactions with metals, carbohydrates, amino acids. It is the majority of my notes for CHEM008C.

EVERYTHING you need to know about CHEM008C is condensed into these study guides. covers topics such as aldol, claisen, dieckmann, Michael, metal catalyzed reactions,carbohydrates,lipids, terpenes.

Notes about Claisen Condensation (analogous to Aldol condensations) and Dieckmann reactions.

Chapter on Pericyclic reactions including full reaction mechanisms for every reaction and Woodward-Hoffman/Orbital analysis for key examinable material. Cycloadditions, sigmatropic rearrangements and electrocyclic reactions.
