Thionyl chloride is an inorganic compound with the chemical formula SOCl 2.It is a moderately volatile, colourless liquid with an unpleasant acrid odour.Thionyl chloride is primarily used as a chlorinating reagent, with approximately 45,000 tonnes (50,000 short tons) per year being produced during the early 1990s, [5] but is occasionally also used as a solvent.
A typical representative organic reaction displaying this mechanism is the chlorination of alcohols with thionyl chloride, or the decomposition of alkyl chloroformates, the main feature is retention of stereochemical configuration. Some examples for this reaction were reported by Edward S. Lewis and Charles E. Boozer in 1952. [2]
Darzens halogenation is the chemical synthesis of alkyl halides from alcohols via the treatment upon reflux of a large excess of thionyl chloride or thionyl bromide (SOX 2) in the presence of a small amount of a nitrogen base, such as a tertiary amine or pyridine or its corresponding hydrochloride or hydrobromide salt.
It is also more expensive than thionyl chloride so it tends to be used on a smaller scale. This reaction involves conversion of N,N-dimethylformamide to the imidoyl chloride derivative (chloromethylene(dimethyl)ammonium ion (CH 3) 2 N + =CHCl), akin to the first stage in the Vilsmeier–Haack reaction. The imidoyl chloride is the active ...
General chemical structure of an acyl chloride. In organic chemistry, an acyl chloride (or acid chloride) is an organic compound with the functional group −C(=O)Cl. Their formula is usually written R−COCl, where R is a side chain. They are reactive derivatives of carboxylic acids (R−C(=O)OH).
The von Braun amide degradation is the chemical reaction of a monosubstituted amide with phosphorus pentachloride or thionyl chloride to give a nitrile and an organohalide. [1] It is named after Julius Jacob von Braun, who first reported the reaction. [2] [3] The von Braun amide degradation
Susie Coughlin was concerned when her daughter struggled with reading skills at her public school. The mom of two was disappointed her district didn't teach phonics as part of its literacy program.
Oxidative coupling of phenols is a chemical reaction wherein two phenolic compounds are coupled via an oxidative process. Oxidative phenol couplings are often catalyzed by transition metal complexes including V , Cr , Mn , Cu , Fe , among others.
