A Convenient Preparation Method of the Vinylic Halide Isomer of Chlorotrimethylsilyl Enol Ethers

Abstract
Reaction of trimethylsilyliodide (generated in situ from trimethylsilylchoride and sodium iodide) in the presence of triethylamine in acetonitrile with α-chloroketones yields the vinylic halide isomer of chlorotrimethylsilyl enol ethers.
