Room-Temperature, Water-Promoted, Radical-Coupling Reactions of Phenols with tert-Butyl Nitrite

Abstract

A radical–radical cross-coupling reaction of phenols with tert-butyl nitrite has been developed with the use of water as an additive. This method allows the construction of C–N bonds under an air atmosphere at room temperature, providing the ortho-nitrated phenol derivative in moderate to good yields.

Key words

radical reaction - cross-coupling - phenols - butyl nitrite - C–N bond formation - nitrophenols

• 9 Nitration of Phenols 1; General Procedure To a Schlenk tube were added phenol 1 (0.3 mmol), tert-BuONO (2a; 0.6 mmol), H₂O (0.6 mmol), and THF (2 mL), and the mixture was stirred at 25 °C under air atmosphere for the indicated time until the starting material was completely consumed (TLC). The mixture was extracted with EtOAc (3 × 10 mL), and the organic extracts were dried (Na₂SO₄) and concentrated under vacuum to give a crude product that was purified by column chromatography (silica gel, hexane/EtOAc, 5/1). 1-Nitro-2-naphthol (3aa) Yellow solid; yield: 0.0427 g (75%); mp 102.7–103.4 °C. ¹H NMR (300 MHz, CDCl₃): δ = 12.19 (s, 1 H), 8.88 (d, J = 8.7 Hz, 1 H), 7.97 (d, J = 9.0 Hz, 1 H), 7.78 (d, J = 7.8 Hz, 1 H), 7.70 (t, J = 7.8 Hz, 1 H), 7.48 (t, J = 7.5 Hz, 1 H), 7.21 (d, J = 9.0 Hz, 1 H). ¹³C NMR (75 MHz, CDCl₃): δ = 158.9, 139.3, 131.0, 129.4, 128.7, 126.9, 125.7, 123.2, 119.4, 119.3.
