Stuff will turn red when these compounds are exposed to Fehling's solution and other sugar tests; oxidation of these compounds similarly creates a "silver mirror" in the Tollens test.
One form of this functional group is created when secondary amines replace primary amines in a pyridine ring-opening reaction. In the Oxo Diels-Alder reaction, a dihydropyran ring is formed when a diene reacts with one of these. The Tishchenko reaction disproportionates one of these compounds lacking an alpha-hydrogen in presence of an alkoxide to yield an ester; they are subjected to a similar base-induced procedure to yield an alcohol and carboxylic acid in the (*) Cannizzaro reaction. The Corey-Fuchs reaction produces alkynes from these compounds, whose simplest member is produced from the oxidation of methanol. Stuff will turn red when these compounds are exposed to Fehling's solution and other sugar tests; oxidation of these compounds similarly creates a "silver mirror" in the Tollens test. Consisting of a carbonyl bonded to an R group and a hydrogen, for 10 points, name this functional group contrasted with ketones whose simplest member is formaldehyde.
