An efficient copper-catalyzed arylation reaction of 1-acyl-1H-1,2,3-benzotriazoles with diaryliodonium salts via C–N activation is explored. The reaction is conducted regioselectively to form 1-aryl-1H-1,2,3-benzotriazoles in MeCN at 80 °C in the presence of cesium carbonate. 29 examples are given with the product yield of up to 84%. The probable reaction mechanism is proposed.

Paragraph 0102-0105, (2017/08/25)
The invention discloses a method for synthesizing aryne new method, which belongs to the technical field of chemical industry. The method firstly to sulfuryl fluoride with 2 - trialkyl (or aryl) silicon phthalimidephenol as the starting material for synthesizing new aryne precursor, then make it with alkali is produced aryne (active intermediates). The active intermediate in situ chemical reaction with other compounds. The method substrate fluorine atom content is low, with high atom economy, and effectively reduce the reaction and post-processing in the process cause pollution to the environment and luminescent harm to human body; at the same time cheap and easy to obtain, synthesis technique is simple, mild reaction conditions, post-processing process is simple, the productive rate is high, and is favorable for industrial production.
