Facile preparation and Suzuki-Miyaura cross-coupling of N-2-alkylated 2H-1,2,3-triazole 4-boronates

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.
