| Reaction = }} The Perkin reaction is an organic reaction developed by William Henry Perkin that is used to make cinnamic acids. It gives an α,β-unsaturated aromatic acid by the aldol condensation of an aromatic aldehyde and an acid anhydride, in the presence of an alkali salt of the acid. The alkali salt acts as a base catalyst, and other bases can be used instead. Several reviews have been written.〔House, H. O. (1972) ''Modern Synthetic Reactions'', W. A. Benjamin, Menlo Park, California, 2nd ed, pp. 660–663〕 ==Reaction mechanism== The above mechanism is not universally accepted, as several other versions exist, including decarboxylation without acetic group transfer.〔Bansal, Raj K.
