Kinetic results support a pathway proceeding via a rate-determining oxidative decomposition of a chromate ester of an aldehyde hydrate. A cyclic transition state is suggested; being a H¨ąckel-type system (4n + 2), this would be an allowed process. The deuterium isotope effect for the oxidation of acetaldehyde (kH / kD = 6.4) indicated a carbon-hydrogen cleavage rather than a carbon-carbon cleavage %K kinetics %K oxidation %K aliphatic aldehydes %K quinolinium dichromate %K mechanism %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=151759
