Cinnamic Acid from Benzaldehyde and Acetic Acid?
I found this while reading through Google Books, where they mention that cinnamic acid can be obtained by the reaction of benzaldehyde with acetic
acid, using HCl or ZnCl2. They don't mention a yield, but do reference German journal article. I can't read German, and would have a hard time even
finding the article.
Does this sound plausible? I am thinking the article probably actually uses acetic anhydride.

Sounds plausible, though not at 16 Celsius but at 160 Celsius, in a sealed tube!

I have seen that method with acetic anhydride, but with 160-180 degrees. Higher than boiling temperatures are out of my reach.
