Enolate - Study guides, Class notes & Summaries

Organic Chemistry: Structure and Function by Neil E. Schore and K. Peter C. Vollhardt. Chapter 23 overview containing mechanisms with ester enolates. Mechanisms include Claisen/Dieckmann Condensation, Acetoactetic ester synthesis, masonic ester synthesis, and Michael addition.

his chapter introduces students to the organic compounds known as aldehydes and ketones, which are characterized by the carbonyl functional group (C=O). Here's an overview of what is usually covered in this chapter: Introduction to Aldehydes and Ketones: Aldehydes and ketones are organic compounds with a carbonyl group, which consists of a carbon atom doubly bonded to an oxygen atom. In aldehydes, the carbonyl group is at the end of the carbon chain, while in ketones, it is found within ...
