The Suzuki–Miyaura cross-coupling reaction of 1-aryltriazenes with arylboronic acids catalyzed by a recyclable polymer-supported Pd–NHC complex catalyst has been realized for the first time. The polymer-supported catalyst can be re-used several times still retaining high activity for this transformation. Various aryltriazenes were investigated as electrophilic substrates at room temperature to give biaryls in good to excellent yields and showed good chemoselectivity over aryl halides in the reactions.

We describe the successful cross-coupling of diaryl ditellurides with arylboronic acids by using copper(I) thiophene-2-carboxylate (CuTC) under mild conditions. Although other studies have reported that highly polar solvents (such as DMSO) or bases are required, this reaction was completed by using CuTC and common solvents under neutral conditions at room temperature. This cross-coupling reaction was performed with diaryl ditellurides and arylboronic acids bearing various groups, affording the corresponding diaryl tellurides in good to excellent yields.
