An ester wax is obtained by a condensation reaction of carboxylic acid and alcohol; wherein the carboxylic acid contains a single kind of saturated linear monocarboxylic acid having 14 to 30 carbon atoms as a main component, and the single kind of carboxylic acid is contained in a ratio of ...
The proposed enolate has been trapped in the case ofamide(53) but there was no report if this could be accomplished on the ester substrates (equation39). In general the amides did give higher yields of ketone and less tertiary alcohol, but this is expected based purely on the enhanced stab...
An ester is a chemical compound derived from an acid (organic or inorganic) in which at least one –OH hydroxyl group is replaced by an –O– alkyl (alkoxy) group, as in the substitution reaction of a carboxylic acid and an alcohol. Glycerides are fatty acid esters of glycerol; they are...
