Procedure for the Coupling and Reduction of p-Nitroiodobenzene
Catalyzed by PdAuNPs@COF: To each of two Schlenk tubes were
added p-nitroiodobenzene (7.5 mg, 0.03 mmol), phenylboronic acid
(4.0 mg, 0.033 mmol), K2CO3 (62 mg, 0.045 mmol), and PdAuNPs@
COF (1.4 mg, 0.36 µmol) and EtOH/H2O (0.34 mL, 1/1 v/v). The
reaction mixture was stirred for 2 h at 50 °C at nitrogen atmosphere. The
crude product of one tube was extracted with EtOAc and the yield was
determined based on the integration of the proton peaks in the 1H NMR
spectrum of the crude product mixture. To the other tube was added an
aqueous solution of NaBH4 (10 m, 5.0 mL), and the reaction mixture
was stirred for 2 h at 25 °C at nitrogen atmosphere. The crude product
was then extracted with CH2Cl2 and the yield was determined based
