Bound Aldehydes in Butteroil

Chemoselective reduction of aldehydes by ruthenium trichloride and resin-bound formates

A simple, chemoselective transfer hydrogenation of aryl aldehydes with the aid of Amberlite((R)) resin formate (ARF), a stable H-donor, in the presence of catalytic ruthenium trichloride is described. Aromatic aldehydes and 1,2-diketones are reduced efficiently and selectively, while aryl ketones remain unchanged. Several other potentially reducible groups attached to the aromatic moiety are un...

Ketone aldehydes in tissues.

Composition of the Aldehydes of Clostridium Butyricum Plasmalogens. Cyclopropane Aldehydes.

Recent advances in gas-liquid chromatography have permitted the separation and identification of aldehydes derived from plasmalogens, and a number of analyses of aldehydes from animal plasmalogens have been reported (l-3). Bacterial plasmalogens, on the other hand, have only recently been discovered, and no analyses of their fatty aldehydes are available (4-6). Such analyses would be of particu...

Interaction of amines with ketone aldehydes and unsaturated aldehydes.

The optical changes occurring during the interaction of amines with ketone aldehydes or unsaturated aldehydes are accompanied by strong electron spin resonance signals, and can thus be explained as due to the transfer of one whole electron in the ground state.

Cyanobacterial aldehyde deformylase oxygenation of aldehydes yields n-1 aldehydes and alcohols in addition to alkanes.

Aldehyde-deformylating oxygenase (ADO) catalyzes O2-dependent release of the terminal carbon of a biological substrate, octadecanal, to yield formate and heptadecane in a reaction that requires external reducing equivalents. We show here that ADO also catalyzes incorporation of an oxygen atom from O2 into the alkane product to yield alcohol and aldehyde products. Oxygenation of the alkane produ...
