O ressurgimento da química de benzino com sililaril triflatos no contexto das reações de inserção em ligações sigma The benzyne chemistry revival with silylaryl triflates in the context of insertion reactions into sigma bonds

Abstract

In this paper we gathered articles concerning insertion reactions of arynes, exclusively generated from 2-(trimethylsilyl)aryl triflates in the presence of fluoride ions, in substrates bearing nucleophilic and electrophilic portions separated by sigma bonds. Accordingly, we stand out the great importance and versatility of such transformations in the preparation of highly functionalized aromatic systems, which are hardly synthesized in just one step for other methods.
