Phenyllithium is an organometallic agent with the empirical formula C 6 H 5 Li. It is most commonly used as a metalating agent in organic syntheses and a substitute for Grignard reagents for introducing phenyl groups in organic syntheses. [ 3 ]
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
The erythro betaine can be converted to the threo betaine using phenyllithium at low temperature. [18] This modification affords the E-alkene. The Schlosser variant of the Wittig reaction. Allylic alcohols can be prepared by reaction of the betaine ylide with a second aldehyde. [19] For example: An example of the Schlosser variant of the Wittig ...
Phenethyl alcohol, or 2-phenylethanol, is an organic compound with the chemical formula C 6 H 5 CH 2 CH 2 OH. It is a colourless liquid with a pleasant floral odor. It occurs widely in nature, being found in a variety of essential oils. It is slightly soluble in water (2 ml per 100 ml of H 2 O), but miscible with most organic solvents.
In organometallic chemistry, organolithium reagents are chemical compounds that contain carbon–lithium (C–Li) bonds.These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation. [1]
Phenyl groups are usually introduced using reagents that behave as sources of the phenyl anion or the phenyl cation. Representative reagents include phenyllithium (C 6 H 5 Li) and phenylmagnesium bromide (C 6 H 5 MgBr). Electrophiles are attacked by benzene to give phenyl derivatives: + + + +
Ethanol (data page) provides detailed information about the chemical properties, physical properties, and safety measures of ethanol.
Those with five organic substituents are rare, although P(C 6 H 5) 5 is known, being derived from P(C 6 H 5) 4 + by reaction with phenyllithium. [citation needed] Phosphorus ylides are unsaturated phosphoranes, known as Wittig reagents, e.g. CH 2 P(C 6 H 5) 3. These compounds feature tetrahedral phosphorus(V) and are considered relatives of ...
