Self-condensation is a natural response in which a synthetic compound containing a carbonyl gathering acts both as the electrophile and the nucleophile in an aldol condensation. A condensation response in which two of a similar atom are consolidated. This aldol condensation is a self-condensation response since two particles of CH3)2CO consolidate to frame the item. This blended Claisen buildup is not a self-condensation response in light of the fact that the two ester reactants are not indistinguishable.
