Reaction Conditions:
with iodine;oxygen;trifluoroacetic acid in methanol;ethyl acetate for 20 h;Irradiation;
Steps:
Photooxidation; Typical Procedure
General procedure: A solution of trans-4,4′-di-tert-butylstilbene (1a) (0.15mmol), I2 (0.015 mmol), and TFA (0.03 mmol) in dryMeOH-EtOAc (1:2 mL) was stirred in a Pyrex test-tube under air (open), and externally irradiated with four 22 W fluorescent lamps for 20 h. The mixture was quenched withaq Na2S2O3 solution and extracted with EtOAc (3 × 5 mL). The combined organic layer was washed with brine (20 mL)and aq HCl (2 M, 2 × 20 mL), dried over MgSO4 and concentrated in vacuo. Purification of the crude residue by column chromatography (hexane-EtOAc, 50:1) provided 4-tert-butylbenzaldehyde (2a) (41.1 mg, 84%).
