Facile preparation and Suzuki–Miyaura cross-coupling of N-2-alkylated 2H-1,2,3-triazole 4-boronates
摘要:
The preparation of N-2 substituted 2H-1,2,3-triazoles substituted at C-4 with an organometallic moiety has no recognised precedent. Herein, we report their efficient preparation via CH borylation and demonstrate their successful application to aryl-aryl Suzuki cross-coupling. (C) 2012 Elsevier Ltd. All rights reserved.

A regioselective electrochemical C–H amination method to synthesize N2-substituted 1,2,3-triazole using easily accessible ethers has been developed. Various substituents, including heterocycles, have a good tolerance, and 24 examples were obtained in moderate to good yields. Control experiments and DFT calculation investigations demonstrate that the electrochemical synthesis undergoes a N-tosyl 1,2
