Abstract

Stimulated by Baghersad's result, we envisioned that aryl halides might go through a similar coupling reaction, and thereby giving a more economic approach for preparing aryl carbamates. With this idea in mind, we conducted a coupling of 4-iodoanisole with potassium cyanate. It was found that under the catalysis of 20 mol% CuI and 20 mol% N,N-dimethylglycine, the reaction took place in n-BuOH at 100 °C to afford the desired ...
