# Effect of Clemmensen reduction on carboxylic acids

Does the Clemmensen reduction have any effect on the carboxyl group $\ce{-COOH}$ if it is attached to some organic compound? If yes, what does it get reduced to?

• You're putting zinc in acid, so there will be a reaction, but maybe not the one you wanted? – Zhe Jan 24 '17 at 1:34
