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.


Incompatible with strong acids, strong bases, strong oxidizing agents and strong reducing agents.

The combination with PPh3 is superior to the popular CCl4-PPh3 system for conversion of carboxylic acids to acyl chlorides: Tetrahedron Lett., 40, 5323 (1999). It also converts allylic alcohols to the corresponding chlorides: Russ. J. Org. Chem., 31, 1019 (1995).

In the presence of a base, e.g DBU, reacts with alcohols to form trichloroacetimidates, which are a useful means of protection, readily cleaved by TsOH/MeOH, DBU/MeOH or Zn/NH4Cl: Synlett, 753(1999). These imidates are activated towards displacement by nucleophiles. Glycosyl imidates, formed in the presence of a base such as K2CO3 or DBU, are widely applied as glycosyl donors in oligosaccharide synthesis. Reaction with the free OH of the glycosyl acceptor occurs under mild conditions, promoted by a Lewis acid, e.g. BF3 etherate or TMS-OTf, to form, respectively, either the ß- or ɑ-glycoside as the major product: Angew. Chem. Int. Ed., 25, 212 (1986). For reviews, see: Chem. Rev., 93, 1503 (1993); Adv. Carbohydr. Chem. Biochem., 50, 21 (1994); Contemp. Org. Synth., 3, 173 (1996). The imidates of allylic alcohols, prepared using NaH, or, more conveniently, KOH under phase-transfer conditions: Tetrahedron Lett., 37, 1481 (1996), undergo a [3,3]-sigmatropic rearrangement to derivatives of allylamines: J. Am. Chem. Soc., 96, 597 (1974); 98, 2901 (1976). For an example, see: Org. Synth. Coll., 6, 507 (1988). Review: Acc. Chem. Res., 13, 218 (1980):

Aromatic aldoximes are dehydrated to nitriles by a similar cyclic mechanism: J. Org. Chem., 38, 2241 (1973).

Reacts with hydrogen peroxide, to give, in situ, peroxytrichloroacetamidic acid, a reagent for the epoxidation of alkenes under essentially neutral conditions: J. Org. Chem., 48, 888 (1983).
