| Application: | Tebbe reagent can be used: • For the conversion of carbonyl groups of chlorophyll derivatives into the corresponding exo-methylene (or vinylidene) groups. • In the synthesis of β-C-glycosides from 3-OH glycol esters. • As a versatile methylenation reagent for the conversion of ketones and aldehydes to olefins. It offers facile reaction with hindered ketones and allows the conversion of esters to vinyl ethers. • To olefinate aldehydes. • To methylenate a chiral polyhydroxyketone with high diasteroselctivity. |
| General description: | Tebbe reagent is a Lewis acid stabilized organometallic compound, which is used to transform carbonyl groups into β-substituted methylenes. It also reacts with a wide range of carbonyl compounds, including esters, amides, and lactones to yield corresponding olefins. |
