yield of 28.91% benzoin was obtained. The MP of benzoin was 127O-130O C and the IR spectra displayed a carbonyl peak at 3415 cm-1 ‚‚which represents and OH functional group. The second step of the reaction was to oxidize benzoin to form benzil; this reaction yielded 27.04% benzil. The MP of the benzil was 91O-93O C and the IR spectra revealed no OH functional groups. The last step of the synthesis was a double aldol condensation reaction to form tetraphenylcyclopentadienone; this reaction had a yield

compounds consisting of a carbonyl adjacent to an ether linkage. They are derived by reacting an oxo acid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group‚ and most commonly from carboxylic acids and alcohols. That is‚ esters are formed by condensing an acid with an alcohol. Esters are ubiquitous. Most naturally occurring fats and oils are the
