5‐(Cyano)dibenzothiophenium Triflate: A Sulfur‐Based Reagent for Electrophilic Cyanation and Cyanocyclizations
The synthesis of 5‐(cyano)dibenzothiophenium triflate 9, prepared by activation of dibenzo[b,d]thiophene‐5‐oxide with Tf(2)O and subsequent reaction with TMSCN is reported, and its reactivity as electrophilic cyanation reagent evaluated. The scalable preparation, easy handling and broad substrate sc...
