EXPERIMENT OBJECTIVE The aim of this experiment is synthesize hexaphenylbenzene via an aldol condensation reaction‚ followed by a Diels-Alder [4+2] cycloaddtion. This is final step in the multistep synthesis pathway to form hexaphenylbenzene‚ and uses the products of the previous experiments: benzil and diphenylacetylene REACTION DIAGRAM TABLE OF REAGENTS BENZIL DIBENZYL KETONE TRITON B 40wt% IN METHANOL (1.79 M) TRIETHYLENE GLYCOL TETRAPHENYL-CYCLOPENTA-DIENONE DIPHENYL ACETYLENE

The purpose of this experiment was to perform a wittig reaction‚ the horner-emmons wittig specifically‚ reacting an aldehyde with an ylide to make an alkene. This particular variation of the wittig reaction has several advantages: It gives only the trans product; it uses a much milder base that is easier to handle; and it gives a water soluble byproduct which is easy to separate from the product. The reason that these advantages occur is a change in the structure of the ylide. Instead of a tripheylphosphine

When the OH- reacts with alkyl halide (iii) or acyl halide (iv)‚ the conjugate base will tend to react with the unreacted carbonyl compound by means of an aldol condensation reaction as shown in equation (vi)1.
