Abstract
Present work is dedicated to studies of kinetic regularities of α-ethylacrolein and crotonaldehyde oxidation in methanol, allyl alcohol and glycidol. Kinetic model of the reaction has been designed based on experimental data. Rate constants of hydrogen peroxide disappearance and rate constants of unsaturated acid and its ester formation for both aldehydes in different alcohols at various catalyst concentrations and temperatures have been calculated. The reaction activation parameters have also been calculated. Dependences of ester/ acid ratio on the reaction conditions have been ascertained. Our results indicate the dependence of the reaction rate and the reaction products composition on type of aldehyde and alcohol.
Keywords: Crotonaldehyde, ester/acid ratio, α-ethylacrolein , H2SeO3 catalyst, Kinetic and activation parameters of reaction, Oxidation with hydrogen peroxide, Oxidative alkoxylation

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
