OXIDATION OF α-HYDROXY ACIDS WITH QUINOLINIUM DICHROMATE - A KINETIC ATUDY

Article abstract of DOI:10.1135/cccc19931624

Oxidations od lactic acid, α-hydroxyphenyllactic acid and its 4-chloro derivative with quinolinium dichromate (QDC) in 30percent (v/v) aqueous acetic acid at 303 K are first-order on QDC and first-order in hydroxy acids.The reactions are acid-catalyzed and a medium of low dielectric constant favours the oxidation.The products are the corresponding aldehydes.Thermodynamic parameters are evaluated and a mechanism involving a C-C bond cleavage is proposed.
