Cannizzaro reaction
Cannizzaro reaction[kän·it′sär·ō rē′ak·shən] (organic chemistry) The reaction in which aldehydes that do not have a hydrogen attached to the carbon adjacent to the carbonyl group, upon encountering strong alkali, readily form an alcohol and an acid salt. Cannizzaro reaction
Can·niz·za·ro re·ac·tion (kahn-i-tsah'rō), formation of an acid and an alcohol by the simultaneous oxidation of one aldehyde molecule and reduction of another; a dismutation: 2RCHO → RCOOH + RCH2OH; when the aldehydes are not identical, this is referred to as a crossed Cannizzaro reaction. [Stanislao Cannizzaro] Can·niz·za·ro re·ac·tion (kah'nēts-tsah'rō rē-ak'shŭn) Formation of an acid and an alcohol by the simultaneous oxidation of one aldehyde molecule and reduction of another; a dismutation: 2RCHO → RCOOH + RCH2OH; when the aldehydes are not identical, this is referred to as a crossed Cannizzaro reaction. [Stanislao Cannizzaro]Cannizzaro, Stanislao, Italian chemist, 1826-1910. Cannizzaro reaction - formation of an acid and an alcohol by the simultaneous oxidation of one aldehyde molecule and reduction of another. |
