This reaction is related to several classic named reactions: The acylated reaction product can be converted into the alkylated product via a Clemmensen or a Wolff-Kishner reduction. [17] The Gattermann–Koch reaction can be used to synthesize benzaldehyde from benzene. [18] The Gatterman reaction describes arene reactions with hydrocyanic acid ...
Phenyl acetate is the ester of phenol and acetic acid.It can be produced by reacting phenol with acetic anhydride or acetyl chloride.. Phenyl acetate can be separated into phenol and an acetate salt, via saponification: heating the phenyl acetate with a strong base, such as sodium hydroxide, will produce phenol and an acetate salt (sodium acetate, if sodium hydroxide were used).
An ester of a carboxylic acid. R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′).

In addition to the ordinary thermal phenyl ester reaction a photochemical variant is possible. The photo-Fries rearrangement can likewise give [1,3] and [1,5] products, [7] [8] which involves a radical reaction mechanism. This reaction is also possible with deactivating substituents on the aromatic group. Because the yields are low this ...
Reduction of tosylate esters gives the hydrocarbon. Thus, tosylation followed by reduction allows for the deoxygenation of alcohols. Structures of the 7-norbornenyl cation with p-orbital stabilization. In a famous and illustrative use of tosylate as a leaving group, the 2-norbornyl cation was formed by an elimination reaction of 7-norbornenyl ...
Such species convert by a Wolff rearrangement to give an ester in the presence of alcohols. When applied to cyclic α-diazoketones, ring contraction occurs. [3] [4] In the case of steroids, this reaction has been used to convert cyclopentanone groups to cyclobutanyl derivatives. [5]
Generic structure of an organosulfate, where R is an organyl group. In organosulfur chemistry, organosulfates are a class of organic compounds sharing a common functional group with the structure R−O−SO − 3. The SO 4 core is a sulfate group and the R group is any organic residue.
The Dakin oxidation (or Dakin reaction) is an organic redox reaction in which an ortho- or para-hydroxylated phenyl aldehyde (2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde) or ketone reacts with hydrogen peroxide (H 2 O 2) in base to form a benzenediol and a carboxylate. Overall, the carbonyl group is oxidised, whereas the H 2 O 2 is reduced.
