Abstract Introduction The acylation of the α carbon position of a carbonyl group is one of the greatest breakthroughs that has benefited chemists in organic synthesis particularly when in need of building a carbon skeleton of interest in a molecule. For one to be able perform this acylation technique‚ there are two mar approaches which are employable. The first method involves the deprotonation of the α-Carbon atom which has a pKa known to be ̴20 through the use of a strong base for instance

Purpose: To synthesize 1‚2‚3‚4-tetraphenylnaphthalene through a two-step synthesis. The aldol condensation reaction between benzil and dibenzyl ketone forms 2‚3‚4‚5-tetraphenylcyclopentadienone‚ which then reacts with a benzene formed by anthranilic acid and isoamyl nitrate in order to yield 1‚2‚3‚4-tetraphenylnaphthalene. Reaction Equation A: Synthesis of 2‚3‚4‚5-tetraphenylcyclopentadienone: A solution of 4 capsules potassium hydroxide (0.5g) and 5mL anhydrous ethanol was prepared
