General Introduction

Up to the mid-1950s, sodium was undoubtedly the most important of the alkali metals to the organic chemist. Sodium salts were used in displacement reactions, and sodium ethoxide in ethanol was one of the most common reagents for the preparation of carbanion intermediates derived from carbonyl and related compounds for use in aldol addition and condensation reactions. Sodium metal was typically stored in mineral oil and was soft enough to be converted into wire for direct reaction with the lower primary alcohols. A sodium press was to be found in every synthetic laboratory. Sodium amalgam moderates the reducing activity of sodium and was commonly used for various reductions.
