You did not prepare your own chloride (PhCH2PPh3Cl, Wittig salt). Write a reaction showing how the Wittig salt is prepared from benzyl chloride (PhCH2Cl).

The reaction of preparation of the Wittig salt occurs as follows:

C7H7Cl + C18H15P = C25H22ClP

Where C7H7Cl = benzyl chloride

C18H15P = Triphenylphosphine

C25H22ClP = chloride

It is a synthesis reaction

Explanation:

To prepare the Wittig salt, 2.6 g of triphenylphosphine and 1.4 g of benzyl chloride, plus 15 mL of toluene should be added to a round bottom flask with magnetic stirring. It is placed in a bath and heated to reflux with refrigerant for 12 hours. Chloride will precipitate as colorless crystals, it must be filtered to collect them. These crystals are washed with petroleum ether at a temperature between 50-70°C and dried with heating for 1 h.
