Why does cinnamaldehyde pass the ferric chloride test?

Dirk Kok  Follow

I think the cinnamaldehyde gives $\ce{FeCl3}$ test due the similar reason why acetic acid can give $\ce{FeCl3}$ test as $\ce{Fe^3+}$ can act as oxidizing agent.

As in case of acetic acid $\ce{Fe(CH3COO)3}$ (red colour) is formed, a similar complex may be produced.

True enough but that doesnt account for a necessary, definitive color change.More
