Description and Uses
The 2,2,2-Trichloroethyl (TCE) moiety of 2,2,2-trichloroethanol is mainly used as a protecting group for acids, acetals and also phosphoryl groups of nucleotides. It can be easily cleaved by zinc reduction.
Some of its other application include:
- Conversion of per-O-acetylated sugars to per-O-acetylated trichloroethyl derivatives.
- Preparation of TCE ester of chlorosulfuric acid.
- Preparation of 2,2,2-trichloroethyl acetimidate hydrochloride.
