The mixture was swirled for 10 minutes. 2.4 g of ferrous chloride hydrate and 12 ml of dimethyl sulfoxide were added to a 125 ml Erlenmeyer flask. The FeCl2 was warmed in a warm water bath for five minutes‚ and then cooled in an ice bath until 10°C was reached. The solution was then transferred into a separatory funnel‚ and was added to the

The SN2 reaction requires three qualities: a strong nucleophile‚ a good‚ unhindered leaving group‚ and a polar‚ aprotic solvent. For our reaction‚ we have all three bases covered. The nucleophile is an alkoxide‚ a deprotonated alcohol. Technically‚ because our alcohol is a phenol‚ the conjugate base is called a phenoxide. Phenol itself has a pKa of about 10‚ but our alcohol has more resonance opportunities‚ so the pKa is down around 8. This is sufficiently acidic for use of weak base like K2CO3 for
