Abstract

Self-assembled aggregates of 7,10-dibromo-2,3-dicyanopyrazinophenanthrene which act as a new organophotocatalyst in combination with Ni catalyst for the Caryl–Oacyl cross-coupling reactions of carboxylic acids with aryl halides are described. This visible-light-induced Caryl–Oacyl bond-formation reaction proceeds smoothly to afford aryl esters with satisfactory to excellent yields.

Key words

7,10-dibromo-2,3-dicyanopyrazinophenanthrene - aggregates - organophotocatalyst - carboxylic acids - aryl iodides - esterification

  • 18 p-Carbomethoxyphenyl p-tert-Butylbenzoate (3e); Typical Procedure To a dried 20 mL reaction tube was charged with 4-(tert-butyl)benzoic acid (1e, 35.7 mg, 0.3 mmol), 4-iodobenzoate (2a, 52.4 mg, 0.2 mmol), DCPP2 (4.4 mg, 5 mol%), nickel(II) chlorine·diglyme (4.4 mg, 10 mol%), and dtbbpy (5.4 mg, 10 mol%). The tube was capped. After evacuated and backfilled nitrogen three times, DMF (3 mL) was added via a gastight syringe, followed by the addition of N-tert-butyl-isopropylamine (95 μL, 0.6 mmol). The reaction mixture was stirred under the irradiation of a 10 W 430 nm blue LED at 40 °C for 24 h. After 24 h, the mixture was quenched with water and extracted with ethyl acetate (3 × 10 mL). The combined organic layers were dried over Na2SO4 and concentrated under vacuo. The residue was purified by flash column chromatography on silica gel (ethyl acetate/petroleum ether = 1: 5) to afford a white solid (56.5 mg, 90%); mp 115–117 °C. 1H NMR (400 MHz, CDCl3): δ = 8.14–8.11 (m, 4 H), 7.55–7.53 (m, 2 H), 7.31–7.28 (m, 2 H), 3.93 (s, 3 H), 1.37 (s, 9 H). 13C NMR (100 MHz, CDCl3): δ = 166.4, 164.6, 157.8, 154.7, 131.2, 130.1, 127.6, 126.3, 125.7, 121.8, 52.2, 35.2, 31.1. IR: ν = 3422, 3134, 1639, 1400, 1122, 1035, 962, 601, 561 cm–1. HRMS (ESI): m/z calcd [M + H]+: 313.1440; found: 313.1436.
