Definition of carbanion in English: carbanionnoun kɑːˈbanʌɪən-ˌīˌän Chemistry An organic anion in which the negative charge is located on a carbon atom. Example sentencesExamples - They react with water and alcohols in what are essentially acid-base reactions, as if they contained a carbanion; they will also remove protons that are much less acidic than those of water and alcohols.
- Two important examples of stable carbanions are the cyanide anion (NC -) and the metalocenes.
- As a result, carbonyl compounds can form carbon anions (carbanions) and act as nucleophiles rather than electrophiles.
- The key central intermediate is the carbanion formed as a result of CO2 loss from KP.
- The key intermediates would be a benzylic carbanion, a benzylic radical and a hydroperoxy radical arising from via oxygen trapping.
