WebThe Wolf-Kishner reduction is a reaction used in Organic Chemistry to convert carbonyl functionalities into methylene group. The reaction was used to convert an aldehyde or ketone to an alkane using hydrazine, base and thermal conditions. The mechanism begins with the attack of hydrazine of the aldehyde or ketone. WebMolecules which contain two carbonyl functionalities have the possibility of forming a ring through an intramolecular aldol reaction. In most cases two sets of α hydrogens need to be considered. As with most ring forming reaction five and six membered rings are preferred.

In organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes, ketones and carboxylic acids), as part of many larger … See more For organic compounds, the length of the C-O bond does not vary widely from 120 picometers. Inorganic carbonyls have shorter C-O distances: CO, 113; CO2, 116; and COCl2, 116 pm. The carbonyl … See more • Infrared spectroscopy: the C=O double bond absorbs infrared light at wavenumbers between approximately 1600–1900 cm (5263 nm to 6250 nm).
