Ligandless Palladium-Catalyzed Reductive Carbonylation of Aryl Iodides under Ambient Conditions

Abstract

Ligandless palladium-catalyzed reductive carbonylation of aryl iodides for the synthesis of aromatic aldehydes has been developed. This carbonylation process proceeded effectively even under ambient temperature and pressure. In addition, this method enables successive reductive carbonylation of diiodobenzenes to furnish dialdehydes in satisfactory yields. Finally, the nature of the active catalytic species is discussed.

Key words

aromatic aldehydes - aryl iodides - reductive carbonylation - ligandless - ambient conditions

• 14 General Procedure The reaction was carried out in a 25 mL flask was equipped with 4-iodo-4-nitrobenzene (1a, 0.5 mmol, 127.0 mg), Pd(OAc)₂ (0.01 mmol, 2.4 mg), Na₂CO₃ (0.5 mmol, 53.1 mg), NaHCO₃ (0.5 mmol, 42.0 mg), and PEG-400 (2.0 g) before standard cycles of evacuation and back-filling with dry and pure carbon monoxide. Triethylsilane (1.0 mmol, 162.8 μL) was added successively. The mixture was stirred under ambient temperature and pressure for the indicated time. At the end of the reaction, the reaction mixture was poured into a sat. aq NaCl solution (20 mL) and extracted with EtOAc (3 × 15 mL). The organic phases were combined, and the volatile components were evaporated in a rotary evaporator. The residue was purified by column chromatography on silica gel (PE–Et₂O, 50:1) to afford the corresponding product 2a, a light yellow solid (66 mg, 87%); mp 105.9–106.4 °C. ¹H NMR (400 MHz, CDCl₃): δ = 10.13 (s, 1 H), 8.36 (d, J = 8.9 Hz, 2 H), 8.05 (d, J = 8.9 Hz, 2 H) ppm. ¹³C NMR (100 MHz, CDCl₃): δ = 190.3, 151.1, 140.0, 130.4, 124.3 ppm.
