We found that the use of either electron-rich or electron-deficient haloaryltrifluoroborates led to the desired cycloaddition products with good to excellent yields. Furthermore, we successfully carried Out the cross-coupling reactions of the obtained triazoles with various aryl halides by means of the Suzuki-Miyaura reaction in the presence of 3 mol % of Pd(PPh(3))(4) catalyst in a 20% aqueous 1,4-dioxane solution at 100 degrees C; all these reactions yielded complete conversion to the corresponding products. Besides providing a high level of personnel safety, our highly versatile approach allows the preparation of functionalized organotrifluoborates containing 1,2,3-triazoles with retained functionality.
