Aldol polycondensation

WebApr 18, 2024 · Additionally, aldol polycondensation was recently reported as a new route, as it requires neither organometallic monomers nor transition metal catalysts. For … WebAn aldol condensation is a condensation reaction in organic chemistry in which two carbonyl moieties (of aldehydes or ketones) react to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction ), and this is then followed by dehydration to give a conjugated enone. The overall reaction is as follows (where the Rs can be H):
