Description

Application

Synchronous Ar-F and Ar-Sn Bond Formation Through Fluorostannylation of Arynes

Continuous-Flow Synthesis of Trimethylsilylphenyl Perfluorosulfonate Benzyne Precursors

Bromosilyltriflate has been shown to be a useful precursor for the generation of a bromobenzyne intermediate. The bromobenzyne intermediate can be generated in the presence of cesium or potassium fluoride and can be trapped with various dipolariphiles.
