Mark DeWitt 35651743 Chemistry 216 Section 128 Experiment 7: The Wittig Reaction Introduction The purpose of this experiment was to form a carbon-carbon double bond with the elimination of a phosphine oxide. The reaction involved the addition of a phosphorus ylide to an aldehyde. The final product was confirmed through IR spectroscopy. Reaction Results These are the steps that I performed for the experiment: 1. Dissolved 50 mg of 2-chlorobenzaldehyde in 3 mL of CH 2 Cl 2 in a flask with a spin vane. 2. Added 1.2 mol of the ylide portionwise (149 mg). 3. Stirred at room temperature for 2 hours. 4. Performed TLC analysis at 30 minute intervals during these 2 hours. 5. After these 2 hours, evaporated off CH 2 Cl 2 . 6. Added 25% ether in hexane and noted reaction. 7. Passed the solution through a short pad of silica.
