WebQuestion: Complete the mechanism for the following mixed Claisen condensation, in which ethyl propanoate is added dropwise to a solution of ethyl benzoate and ethoxide base, by adding any missing atoms, bonds, charges, nonbonding electrons, and curved arrows. Note the resonance arrow between panels two and three. Add two curved arrows. CH2 CH3 … WebIf resonance is considered, then the resonance structure for an ester (11.42) is more important than that for the thioester (11.43) because there is little C–S π-bond character. In terms of inductive effects, oxygen is more electronegative than sulfur, so 11.45 is lower energy (more favorable) than 11.44; this enhances the acidity of the α-protons. the polo house marbellaWebD) acceptor = ethyl propanoate; donor = diethyl carbonate 50 A Dieckmann condensation of diethyl adipate was carried out by heating with sodium ethoxide.
