How is chalcone formed by aldol condensation?
... The kinetics of chalcone formation via aldol condensation was studied using UV spectrophotometry. Chalcone was formed from substituted benzaldehyde (ArCHO) and acetophenone (Ar'COCH₃) with catalyst sodium hydroxide (NaOH) dissolved in acetonitrile and H₂O or deuterium oxide (D₂O).
Which is the complete mechanism of chalcone formation?
The Complete Mechanism of Chalcone Formation. The rate expression for the formation of chalcone is third order: Rate = k₃ [ArCHO] [Ar'COCH3] [ ⁻OH]. With excess [Ar'COCH₃], the reaction becomes pseudo first order in [ArCHO], where the observed rate constant (kobs) is simply proportional to the concentrations of [Ar'COCH₃] and [⁻OH].
