Kinetics and mechanism of the oxidative cleavage of ketones by quinolinium dichromate

Kinetics and Mechanism of Deamination and Decarboxylation of 2-Aminopentanedioic Acid by Quinolinium Dichromate (QDC) in Aqueous Perchloric Acid Medium

“…The α-hydroxyacids and α-ketoacids are oxidized with QDC, and their reactions are studied kinetically. QDC oxidizes cinnamic and crotonic acids smoothly in N , N -dimethylformamide in the presence of an acid to give aldehydes. − …”
