Abstract

Correction for ‘Transition metal-free aminofluorination of β,γ-unsaturated hydrazones: base-controlled regioselective synthesis of fluorinated dihydropyrazole and tetrahydropyridazine derivatives’ by Juan Zhao et al., Org. Chem. Front., 2018, 5, 1155–1159, DOI: 10.1039/C7QO01105A.

The authors regret that Table 2 was duplicated as Table 3 in the original article. The correct Table 3 is presented below.

Table 3 Scope of NaHCO₃-promoted intramolecular aminofluorination reaction of β,γ-unsaturated hydrazones^a

a Reaction conditions: 1 (0.2 mmol), Selectfluor (0.24 mmol), NaHCO₃ (0.4 mmol), CH₃CN (4 mL), 100 °C, under a nitrogen atmosphere, 1 h. Isolated yields of 3. Ratio determined by ¹⁹F NMR spectroscopy.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
