Description and 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.
