AI Article Synopsis
- The Surzur-Tanner rearrangement is a chemical reaction that transforms 2,2,2-trichloroethyl carboxylates into 1-chloroethenyl carboxylates.
- This reaction is highly efficient and uses a mixture of copper(I) chloride (CuCl) and bipyridine (bpy) as catalysts in boiling DCE (dichloroethane).
- Copper is believed to play a key role in this process by either coordinating with the initial radical or acting as a Lewis acid catalyst.
Article Abstract
[reaction: see text] 2,2,2-Trichloroethyl carboxylates undergo highly efficient dechlorinative Surzur-Tanner rearrangement with 2 equiv of a 1:1 molar mixture of CuCl and bpy in boiling DCE to give 1-chloroethenyl carboxylates in which copper appears to play an important role, probably by coordinating the initial radical or as a Lewis acid catalyst.
