Kinetische Untersuchungen zur Methanolyse von Acetalen

It has been shown that the acid-catalyzed methanolysis of the diethylacetales RCH(OEt)2 of acetaldehyde (R=CH3), propionaldehyde (R = C2H5), butyraldehyde (R = C3H7) and caprylaldehyde (R = C7H15) at temperatures between 283 and 318 K proceeds as a consecutive reaction involving a reversible second step.The pseudo first order rate constants of the three reaction steps, their activation parameters and equilibrium constants were estimated by measuring the concentration-time-curves of starting product, intermediate and final product and using a large excess of methanol.There is a linear dependence be tween rate constants of methanolysis and concentration of the catalyst.

Ozonolysis of Symmetrically 1,2-Disubstituted Ethylenes in HCl/Methanol Solutions: Acid Catalyzed Reactions of Primary Cleavage Products

The ozonolysis of olefins in 1 M anhydrous solutions of hydrogen chloride in methanol at /= 0 deg C was investigated.Upon warm-up of the ozonolysis products, the peroxidic primary fragmentation products were converted into non peroxidic end-products by HCl-catalyzed reactions.Cyclopentene (1a) and cyclohexene (1b), e.g., afforded mixtures of the corresponding α,ω-dialdehydebis(dimethyl acetals) (8), dimethyl α,ω-dicarboxylates (9), and methyl ω-aldehyde dimethyl acetal carboxylates (10).Norbornene (1c) gave a mixture of the correspondingly substituted 1,3-cyclopentane compounds (8c - 10c), phenanthrene (22) gave a mixture of methyl 2'-formyl-2-biphenylcarboxylate (24a), 2,2'-biphenyldicarbaldehyde (24b), and dimethyl 2,2'-biphenyldicarboxylate (24c).A reaction scheme was advanced for the rationalization of the types and the distribution of the products.It was partly substantiated by model reactions.
