Benzoyl chloride Melting point is-1.0 ℃, boiling point is 197.2 ℃, and the relative density is 1.212 (20 ℃), while a flash point is 72 ℃, and refractive index (n20) is 1.554. It is soluble in the ether, chloroform, benzene and carbon disulfide. It can gradually decomposed in water or ethanol, ammonia, which generates benzoic acid, generating benzamide, ethyl benzoate and hydrogen chloride. In the laboratory, it can be obtained by distillation of benzoic acid and phosphorus pentachloride under anhydrous conditions. Industrial production process can be obtained by the use of thionyl chloride benzaldehyde. Benzoyl chloride is an important intermediate for preparing dyes, perfumes, organic peroxides, resins and drugs. It is also used in photography and artificial tannin production, which was formerly used as an irritant gas in chemical warfare.

Application

Benzoyl chloride is used for organic synthesis, dye and pharmaceutical raw material, manufacturing initiator benzoyl peroxide, t-butyl peroxybenzoate, pesticides and herbicides. In pesticides, it is a new insecticide, which is inducible isoxazole parathion (Isoxathion, Karphos) intermediate. Benzoyl chloride is an important benzoyl and benzyl reagent. Most of benzoyl chloride is used in the production of benzoyl peroxide, and secondly for the production of benzophenone, benzyl benzoate, benzyl cellulose. Benzoyl peroxide catalyzes polymerization initiator for the monomer plastic, polyester, epoxy, acrylic resin production, self-curing agent, which is a glass fiber material, fluorine rubber, silicone crosslinking agents, oil refined, bleached flour, fiber decolorizing.

Chemical Properties

Synthesis Reference(s)

Journal of the American Chemical Society, 73, p. 702, 1951 DOI: 10.1021/ja01146a061Synthesis, p. 306, 1983 DOI: 10.1055/s-1983-30314

General Description

Benzoyl chloride appears as a colorless fuming liquid with a pungent odor. Flash point 162 °F. Lachrymator, irritating to skin and eyes. Corrosive to metals and tissue. Density 10.2 lb / gal. Used in medicine and in the manufacture of other chemicals.

Reactivity Profile

Benzoyl chloride reacts violently with protic solvents such as alcohols, with amines and amides (for example dimethylformamide [Bretherick 1979 p. 6] ) and with inorganic bases. Causes the violent decomposition of dimethyl sulfoxide [Chem. Eng. News 35(9): 87 1957]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. Friedel-Crafts acylation of naphthalene using Benzoyl chloride, catalyzed by AlCl3, must be conducted above the melting point of the mixture, or the reaction may be violent [Clar, E. et al., Tetrahedron, 1974, 30, 3296].

Hazard

Highly toxic. Strong irritant to skin, eyes, and mucous membranes, and via ingestion, inhala- tion. Upper respiratory tract irritant. Probable car- cinogen.

Health Hazard

INHALATION: may irritate eyes, nose and throat. INGESTION: causes acute discomfort. SKIN: causes irritation and burning.

Chemical Reactivity

Reactivity with Water Slow reaction with water to produce hydrochloric acid fumes. The reaction is more rapid with steam; Reactivity with Common Materials: Slow corrosion of metals but no immediate danger; Stability During Transport: Not pertinent; Neutralizing Agents for Acids and Caustics: Soda ash and water, lime; Polymerization: Does not occur; Inhibitor of Polymerization: Not pertinent.

Safety Profile

Confirmed carcinogen withexperimental tumorigenic data by skin contact. Humansystemic effects by inhalation: unspecified effects onolfaction and respiratory systems. Corrosive effects on theskin, eyes, and mucous membranes by inhalation.Flammable whe

Potential Exposure

Benzoyl chloride is used as a chemical intermediate; in organic synthesis; to produce other chemicals, dyes, perfumes, herbicides, and medicines.

Shipping

UN 1736 Benzoylchloride, Hazard class: 8; Labels: 8—Corrosive material.

Purification Methods

A solution of benzoyl chloride (300mL) in *C6H6 (200mL) is washed with two 100mL portions of cold 5% NaHCO3 solution, separated, dried with CaCl2 and distilled [Oakwood & Weisgerber Org Synth III 113 1955]. Repeated fractional distillation at 4mm Hg through a glass helices-packed column (avoiding porous porcelain or silicon-carbide boiling chips, and hydrocarbon or silicon greases on the ground joints) gave benzoyl chloride that did not darken on addition of AlCl3. Further purification is achieved by adding 3 mole% each of AlCl3 and toluene, standing overnight, and distilling off the benzoyl chloride at 1-2mm [Brown & Jenzen J Am Chem Soc 80 2291 1958]. Refluxing for 2hours with an equal weight of thionyl chloride before distillation has also been used. [Beilstein 9 IV 721.] Strong IRRITANT. Use in a fume cupboard.

Incompatibilities

May form explosive mixture with air. Contact with heat, hot surfaces, and flames causes decomposition, forming phosgene and hydrogen chloride. Water contact may be violent; forms hydrochloric acid. Reactions with amines, alcohols, alkali metals, dimethyl sulfoxide, strong oxidizers, and metal salts may be violent, causing fire and explosions. Attacks metals in the presence of moisture, forming explosive hydrogen gas. Attacks some plastics, rubber or coatings.

Waste Disposal

Pour into sodium bicarbonate solution and flush to sewer.

Remarkably Efficient Iridium Catalysts for Directed C(sp2)-H and C(sp3)-H Borylation of Diverse Classes of Substrates

Chattopadhyay, Buddhadeb,Hassan, Mirja Md Mahamudul,Hoque, Md Emdadul

supporting information, p. 5022 - 5037 (2021/05/04)

Here we describe the discovery of a new class of C-H borylation catalysts and their use for regioselective C-H borylation of aromatic, heteroaromatic, and aliphatic systems. The new catalysts have Ir-C(thienyl) or Ir-C(furyl) anionic ligands instead of the diamine-type neutral chelating ligands used in the standard C-H borylation conditions. It is reported that the employment of these newly discovered catalysts show excellent reactivity and ortho-selectivity for diverse classes of aromatic substrates with high isolated yields. Moreover, the catalysts proved to be efficient for a wide number of aliphatic substrates for selective C(sp3)-H bond borylations. Heterocyclic molecules are selectively borylated using the inherently elevated reactivity of the C-H bonds. A number of late-stage C-H functionalization have been described using the same catalysts. Furthermore, we show that one of the catalysts could be used even in open air for the C(sp2)-H and C(sp3)-H borylations enabling the method more general. Preliminary mechanistic studies suggest that the active catalytic intermediate is the Ir(bis)boryl complex, and the attached ligand acts as bidentate ligand. Collectively, this study underlines the discovery of new class of C-H borylation catalysts that should find wide application in the context of C-H functionalization chemistry.

One-step Conversion of Amides and Esters to Acid Chlorides with PCl3

Li, Fangshao,Wu, Xiaofang,Guo, Fengzhe,Tang, Zi-Long,Xiao, Jing

supporting information, p. 4314 - 4317 (2021/07/16)

A general and efficient iodine-promoted chlorination of amides and esters with phosphorus trichloride is described. For the first time. Various inactivated amides including secondary and tertiary amides were directly converted to the corresponding acid chlorides in one-step. The substrate scope of methyl esters including aromatic and aliphatic esters was also explored under this system. This method is simple, scalable and wide in scope, which provides an approach to preparation of these acid chlorides.
