Direct Palladium(II)-Catalyzed Synthesis of Arylamidines from Aryltrifluoroborates

[Image: see text] A fast and convenient synthesis of arylamidines starting from readily available potassium aryltrifluoroborates and cyanamides is reported. The coupling was achieved by Pd(II)-catalysis in a one step 20 min microwave protocol using Pd(O(2)CCF(3)), 6-methyl-2,2′-bipyridyl, TFA, and M...

Sumario:[Image: see text] A fast and convenient synthesis of arylamidines starting from readily available potassium aryltrifluoroborates and cyanamides is reported. The coupling was achieved by Pd(II)-catalysis in a one step 20 min microwave protocol using Pd(O(2)CCF(3)), 6-methyl-2,2′-bipyridyl, TFA, and MeOH, providing the corresponding arylamidines in moderate to excellent yields.
