systematic study on the carbonylative transformation of 1-bromo-2-fluorobenzenes with various nucleophiles has been performed. Different types of double nucleophiles, such as N-N, N-C, O-C, and N-S, can be effectively applied as coupling partners. The corresponding six-membered heterocycles were isolated in moderate to good yields. © 2014 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
