Abstract
The reduction of aldehydes by flavohydroquinone to yield the corresponding alcohols and flavoquinone is reported and discussed in view of its relevance to the mechanism of flavin-dependent dehydrogenation and carbonyl activation. With formaldehyde and flavohydroquinone formation of a covalent 5- (HO - CH2) Flred⁻ intermediate species is observed. In a reverse reaction 5-methylflavoquinonium cation undergoes an internal redox reaction to yield flavohydroquinone and formaldehyde.
