Takai reaction is a general carbon-carbon bond-forming reaction in organic chemistry. Takai reaction is also known as takai -Utimoto olefination, This transformation is referred to as the name of Kazuhiko Takai. This olefination is a simple alternative for the Wittig reaction and other complex methods like preparing an E alkene stereoselective (major) isomer. In this method, chromium(II) catalyst was used to prepare (E) configuration of alkenyl halides from corresponding carbonyl compounds like aldehyde and ketones.
