2-chloro-6-(trimethylsilyl)phenyl trifluoromethanesulfonate

2-Chloro-6-(trimethylsilyl)phenyl Trifluoromethanesulfonate is used in the preparation of aryne precursors for selective generation of haloarynes.

Chlorosilyltriflate has been shown to be a useful precursor for the generation of a chlorobenzyne intermediate. The chlorobenzyne intermediate can be generated in the presence of Cesium or Potassium Fluoride and can be trapped with various dipolariphiles.
