Knoevenagel Condensation Preparation of Ethyl 3-Coumarincarboxlate Ivy Akatsa Organic Chemistry Introduction Knoevenagel Condensation uses a compound of the type X-CH2-Y as the carbanion source‚ where X and Y are the electron withdrawing groups such as –CN‚-COOR‚-COR‚ NO2‚ etc. These groups are capable of stabilizing an adjacent carbanion by resonance. So in this experiment‚ the Knoevenagel Condensation of diethyl malonate with aromatic aldehyde salicylaldehyde involves an initial aldol-type
