Trichloroacetonitrile Chemical Properties,Usage,Production
Chemical Properties
colourless to slightly yellow liquid
Uses
Trichloroacetonitrile is involved as a reagent in Overman rearrangement, which is used to prepare alylic amines from allylic alcohols. It is also used to prepare bistrichloroacetimidates from diols leading to dihyrooxazines through acid catalyzed cyclization. Further, it is utilized in the synthesis of trichloroacetimidates by 1,8-Diazobicyclo[5.4.0]undec-7-ene (DBU) catalyzed addition of allylic alcohols. It finds application in the study of the methoxy methyl (MOM) catalyzed aza-Claisen rearrangement.
Uses
Insecticide.
Definition
ChEBI: Trichloroacetonitrile is an aliphatic nitrile and an organochlorine compound.
Production Methods
Trichloroacetonitrile can be obtained by dehydration of trichloroacetamide with phosphorous pentoxide or by chlorination of acetonitrile with chlorine. Vapor phase chlorination in the presence of water and photochemical chlorination in the presence of catalysts such as HgCl2 or AlCl3 have been reported. Trichloroacetonitrile is an organic intermediate used, for example, in the synthesis of the fungicide etridiazole.
Reactions
Trichloroacetonitrile is an efficient dehydrating agent for a range of aldoximes, including aromatic and heterocyclic aldoxime, yielding the corresponding nitriles in moderate to good yields. The dehydration reactions can take place in non-acetonitrile media without the aid of a metal catalyst. In addition, it has been confirmed that trichloroacetonitrile was converted into trichloroacetamide in the reaction. Trichloroacetonitrile and triphenylphosphine convert carboxylic acids to acyl chlorides mildly and rapidly under acid-free conditions[1-2].
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
May be sensitive to light and heat. Trichloroacetonitrile may react with water, steam, acid or acid fumes. Trichloroacetonitrile may hydrolyze under acidic or alkaline conditions. . The reaction of benzene and Trichloroacetonitrile evolves toxic chloroform and HCl gasses. (Hagedorn, F., H.-P. Gelbke, and Federal Republic of Germany. 2002. Nitriles. In Ullman Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA.).
Hazard
Strong irritant to tissue. Questionable carcinogen.
Fire Hazard
Trichloroacetonitrile is combustible.
Safety Profile
Poison by ingestion and intravenous routes. Moderately toxic by inhalation and skin contact. Human mutation data reported. A skin and severe eye irritant. An experimental teratogen. Other experimental reproductive effects. When heated to decomposition or in reaction with water, steam, acid, or acid fumes it produces toxic fumes of CN-, Cl-, and NOx. Used as an insecticide. See also NITRILES and CYANIDE.
Toxicity evaluation
Trichloroacetonitrile (TCAN) is a by-product of the chlorine disinfection of water containing natural organic material. When administered by gavage to pregnant Long-Evans rats in a medium-chain triglyceride vehicle, tricaprylin oil (Tricap), at a volume of 10 ml/kg, TCAN induced fetal cardiovascular anomalies at doses as low as 1 mg/kg/d. Five groups of approximately 20 pregnant female rats received TCAN in CO at 15, 35, 55, and 75 mg/kg/d and in Tricap at 15 mg/kg/d (10 ml/kg closing volume). Corn oil, Tricap, and water served as vehicle controls. Animals were treated by oral intubation on gestation d 6-18 (vaginal plug -= d 0). Five out of 20 dams (75 mg/kg) died during treatment. Adjusted maternal weight gain was lower in females receiving 35 mg/kg TCAN or greater. The mean percent of nonlive implants per litter was elevated at 55 and 75 mg/kg TCAN (CO). The TCAN dose-response curve for fetal (but not maternal)effects was shifted to the right when CO was compared to Tricap. Fetal weight was reduced at 15 mg/kg TCAN (Tricap) and at 55 mg/kg TCAN (CO). When TCAN was administered in CO, the mean frequency of soft-tissue maliformations decreased with significantly fewer septal and great vessel cardiovascular defects observed. The lowest observed adverse effect level for TCAN (CO) was determined to be 35 kg/kg.
