study of the Wittig Reaction is important because it is often used to form alkenes from carbonyl compounds. The purpose of this experiment is to isolate the trans‚ trans-1‚4-diphenyl-1‚3-butadiene‚ which is formed by a Wittig reaction along with the cis‚ trans isomeric diene. The reaction is carried out in two steps. First the Wittig salt is obtained through a simple nucleophilic displacement of chloride ion by triphenylphosphine. When treated with base‚ the Wittig salt forms a ylide which is a carbanion

synthesized and the cis-isomer was subsequently isolated by heating the aqueous solution in a steam bath. The UV-vis spectrum of trans-[Co(en)2Cl2]Cl∙HCl∙2H2O and cis-[Co(en)2Cl2]Cl∙HCl∙2H2O were recorded. The trans isomer has εmax values of 30.24‚ 24.55 and 32.03 mol–1dm3cm-1 at 609.00‚ 449.00 and 400.00nm respectively‚ while the εmax values of cis-[Co(en)2Cl2]Cl are 51.03 mol–1dm3cm-1 and 451.2 mol–1dm3cm-1 and the corresponding λmax are 504.00nm and 451.2 mol–1dm3cm-1 respectively.
