Benzoic acid - Wikipedia

Benzoic acid / b ɛ n ˈ z oʊ. ɪ k / is a white (or colorless) solid with the formula C 6 H 5 CO 2 H. It is the simplest aromatic carboxylic acid.The name is derived from gum benzoin, which was for a long time its only source.Benzoic acid occurs naturally in many plants and serves as an intermediate in the biosynthesis of many secondary metabolites. Salts of benzoic acid are …

Decarboxylation - Wikipedia

Decarboxylation - Wikipedia

Decarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide (CO 2).Usually, decarboxylation refers to a reaction of carboxylic acids, removing a carbon atom from a carbon chain.The reverse process, which is the first chemical step in photosynthesis, is called carboxylation, the addition of CO 2 to a compound. Enzymes that …

Further since electron withdrawing gps. increase the acid strength, therefore both 4 nitrobenzoic acid and 3, 4-dinitrobenzoic acids are stronger acid than benzoic acid. Further due to the presence of additional NO2 gp at m-position wrt COOH gt, 3, 4-dinitrobenzoic acid is a lattice stronger acid than 4-nitrobenzoic acid.

Amide synthesis by acylation - Organic Chemistry

Malonic acid derivatives undergo unusually mild decarboxylation in the presence of N,N′-carbonyldiimidazole (CDI) at room temperature to generate a carbonyl imidazole intermediate in high yield. Subsequent reactions with various nucleophiles in an efficient one-pot process leads to amides, esters or carboxylic acids.
