Chemical Name Amount per 100 Aldrich Catalog # students (g or mL) EH&S Benzyltriphenylphosphonium chloride 10 g B32807 4-bromobenzaldehyde 4.75 g B57400 Ethyl acetate 100 mL 270989 Ethanol 100 mL 459836 Heptane 400 mL 246654 * Potassium phosphate, tribasic 21.3 g P5629 Water 750 mL n/a Traditional Wittig Reaction The Wittig reaction is a classic reaction for converting a carbonyl compound to an olefin through a intermediate. This reaction traditionally proceeds using a hazardous solvent, such as dichloromethane or dimethyl formamide.
