Aledo condensation is a C-C bond forming action between the alpha Carbon of the alder or ketene and carbonyl carbon of another ketene or alder. Aledo condensation is different from Aledo condensation reaction. For Aledo addition reaction, the alpha carbon of one alder or ketene adds to the carbonyl group of the other ketene or alder. This process creates a beta-hydroxyl carbonyl, which is called Aledo. For the Aledo condensation reaction, the beta-hydroxyl carbonyl that the alpha-hydrogen then goes on dehydration to form alpha-beta-unsaturated carbonyl compound.

Melting point of product: 204-ICC Discussion: For the H NORM, there are three distinct regions that can identify the product. The first peak is at 003. 08 (singlet, UH) represents four hydrogen atoms of the five numbered ring. The second peak at ј 3. 85 (singlet, UH) represents the hydrogen atoms of the two methods groups. The last region is from D 6. 95 to 7. 56 (multiple, 1 OH) represents the hydrogen atoms of the benzene rings and the hydrogen atoms of vinyl carbons. From the integration of H NORM spectra, the product is assumed to be 2,5-bibs(4-interdependently)coelenterate, which is a product of p-Mishandled and coelenterate.
The melting range was around 204-ICC. To consider the assumption above, the melting range of product using p-Mishandled and coelenterate is around ICC. The melting range of collected product was pretty close compare to the melting range of possible products using p-Aniseed’s and coelenterate.
