Microwave-Assisted Functionalization of Single-Walled Carbon Nanotubes as a Platform for a Supported Iridium Catalyst

Abstract

Single-walled carbon nanotubes (SWCNTs) were functionalized by treatment with imino esters through 1,3-dipolar cycloaddition activated by thermal 1,2-prototropy. The reaction was optimized and analyzed by using various heating methods. The functionalization afforded pyrrolidino-functionalized nanotubes that were characterized by using several techniques. The ester group was then transformed into the corresponding SWCNT–iridium carboxylate and, as a proof of concept, the product was tested as a catalyst in the hydrogen-transfer reaction of acetophenone to yield 1-phenylethanol.

Key words

• 17 These nanotubes were purchased from Cheap Tubes Inc., Cambridgeport, VT, and they contained some double-walled CNTs.
• 18 Functionalization of SWCNTs; General Procedure A pressure tube equipped with a 1.2 atm valve was charged with a 1 mg/mL suspension of SWCNTs in NMP (40 mL) and the appropriate freshly prepared imino ester 1 (0.8 mmol). The mixture was subjected to microwave irradiation to maintain a temperature of 100 °C for 2 h. The resulting mixture was then centrifuged for 40 min at 7000 rpm, and the functionalized nanotubes were collected, redispersed in EtOAc (10 mL), and recentrifuged (30 min, 7000 rpm): this process was repeated three times. Eventually, the product was dried at a reduced pressure for 24 h. All the samples were characterized (see SI). All the FCNT-3 samples displayed a common peak at 400.1 to 400.7 eV, corresponding to a prolinate nitrogen (see SI).
• 19 Attempts were made to use the carboxylates of rhodium and ruthenium, but we observed leaching of the metals and their low incorporation. Attempts to improve the procedure to form these two metal-supported SWCNTs are currently underway.
• 20 FCNT-Ir: General Procedure The appropriate FCNT-3 was dispersed in acetone (1 mg/mL) and 1 M aq of NaOH was added (1 mL per milligram of nanotubes), and the resulting suspension was stirred at 25 °C for 12 h. The resulting mixture was centrifuged for 40 minutes at 7000 rpm. The functionalized nanotubes were collected, redispersed in MeOH (10 mL), and recentrifuged (30 min, 7000 rpm): this process was repeated three times. The purified functionalized nanotubes (30 mg) were dispersed by ultrasound irradiation in CH₂Cl₂ (30 mL). [IrCP*Cl₂]₂ (5 mg) was added, and the suspension was stirred at 25 °C for 18 h under argon. The resulting mixture was centrifuged for 40 minutes at 7000 rpm. The functionalized nanotubes were collected, redispersed in CH₂Cl₂ (10 mL), and centrifuged again (30 min, 7000 rpm). This process was repeated three times to give a total of 24.75 mg of functionalized FCNT-Ir.
