Ethyl cinnamate to cinnamaldehyde
« on: July 23, 2017, 11:16:02 PM »
If I were to convert ethyl cinninimate to cinnamaldehyde I believe my best option would be to use DIBAL in THF at 0C. Would you agree with this?  Also, if I added aqueous base a hydrolysis reaction would occur but also reaction with the pi bond to form an alcohol would also happen, correct?  Thanks for any help.

Ethyl cinnamate contains a conjugated double bond that can also be reduced via 1,4-DIBAL reduction. Thus, it is better to work at lower temperatures than 0oC, in order to avoid any thermodynamic control.
