An efficient method for the synthesis of N-arylated pyridazinones from potassium 2-furantrifluoroborate and aryldiazonium salts is described. The reaction was run in water at 0-5 degrees C in short reaction times and without any catalyst or additive. A mechanistic proposal is made based on the experimental data and DFT calculations.
