Copper-Catalyzed Direct α-Nitration of Nitrostilbenes with Nitrogen Dioxide

Abstract

A novel and efficient method for the direct α-nitration of nitrostilbenes was developed in which NO₂ was used as the nitro source. This method provided (E)-α-nitrostilbenes derivatives in moderate to good yields. A broad substrate scope, mild and convenient conditions, and high stereoselectivity are important features of this method.

Key words

stilbenes - nitration - nitrogen dioxide - nitroalkenes - ionic process

The tube was placed in an oil bath, which was stirred and heated at 60 °C for 3 h. The mixture was cooled to r.t., and the reaction was quenched with H₂O. The resulting mixture was extracted with CH₂Cl₂ (3 × 30 mL), and the organic layers were combined, dried (Na₂SO₄), and concentrated under vacuum. The crude product was purified by column chromatography [silica gel, hexane–CH₂Cl₂ (2:3)] to give a yellow solid; yield: 274 mg (85%); mp 168–170 °C; R_f = 0.37 (CH₂Cl₂–hexane, 3:2). ¹H NMR (300 MHz, DMSO-d ₆): δ = 9.29 (s, 2 H), 8.71 (s, 1 H), 7.47 (d, J = 7.4 Hz, 1 H), 7.44–7.29 (m, 2 H), 7.20 (d, J = 7.4 Hz, 2 H). ¹³C NMR (126 MHz, DMSO-d ₆): δ = 149.7, 149.6, 139.3, 138.9, 133.2, 131.5, 130.0, 129.1, 125.9, 124.5. HRMS (ESI-TOF): m/z [M + H]⁺ calcd. for C₁₄H₉N₄O₈: 361.0420; found 361.0413.
