Researchers report that carboxylic acids, functional groups contained in biomolecules, drugs, and materials can be readily modified by light-induced organic reactions using an aminocyclopropenone.

(A) This is the structure of stearic acid, an 18-carbon saturated fatty acid. The normal numbering system, starting with the carboxylic acid, is shown in blue. The carbons and oxygens of the ...

Carboxylic acids can carry out the same reactions as other acids, for example the reactions with metals and metal carbonate. Carboxylic acids are weak acids, and will react more slowly than other, ...
