Under the conditions used in this experiment an excess of aldehyde , a "double condensation" occurs by reaction on both sides of the ketone to give the products shown below. Phanerochaete chrysosporium simultaneously degrades lignin and cellulose, whereas the closely related species, Ceriporiopsis subvermispora, also depolymerizes lignin but may do so with relatively little cellulose degradation. This type of reaction proceeds through the creation of a resonance-stabilized enolate ion from one of the carbonyl groups. Introduction Like the Grignard reaction, the Aldol Condensation is an extremely useful carbon-carbon bond-forming reaction in organic chemistry.
