Alkoxydienyl boronates 1a and 1b and alkoxystyryl boronate 2 have been used in various copper mediated cross‐coupling reactions with azoles. A variety of N ‐alkoxydienyl‐ and N ‐styrylazoles have been synthesized under mild conditions. The process utilizes Cu(OAc) 2 in the presence of CsF in CH 2 Cl 2 at room temperature.
