Solvation effects in the dimerization of 2-ethylprop-2-enal

Rate constants for dimerization of 2-ethylprop-2-enal in different solvents cannot be approximated using a single solvent parameter. This is possible only with the aid of multiparameter equations. Polar solvents characterized by a high cohesion energy density accelerate the process.

Substituents influences on the rate of α-alkylacroleins dimerization

Kinetics of α-alkylacroleins dimerization was studied. It was established that both electronic and steric factors affect the process rate, with the prevalence of the latter factors.

Gas chromatography analysis of reaction mixtures from cycloaddition reaction of α-ethylacroleine and ethyl ester α-ethylacrylic acid

The gas chromatography (GC) method was applied for the analysis of reaction mixture from synthesis of 2-carboethoxy-2,5-diethyl-3,4-dihydro-2H-pyran. Relative errors of GC determinations not exceeded more than 7-8%. The reaction optimal conditions were proposed on the basis of such criteria as the conversion of α-ethylacrolein, yields and selectivities of main products by using the GC method.

Synthesis and biological activity of α-alkylacrolein dimers and their derivatives

Dimers of methacrolein and α-ethylacrolein have been obtained and undergo a Cannizzaro reaction to the corresponding pyran alcohols and sodium salts of pyran acids. Their bacteriostatic, bactericidal, and fungicidal properties have been studied.
