YieldReaction ConditionsOperation in experiment
With oxalyl dichloride; N,N-dimethyl-formamide; In dichloromethane; at 0 - 20℃; for 3h;Inert atmosphere; General procedure: To an over-dried 100 mL three-necked flask, the carboxylic acid (10 mmol), DMF (5 drops) and DCM (30 mL) were added under a N2 atmosphere. Oxalyl chloride (1.0 mL, 12 mmol) was added dropwise at 0 C resulting in vigorous bubbling. The mixture was stirred for 3 h at room temperature, and the solvent was then removed in vacuo. The resulting acid chloride was used immediately without further purification. To a solution of the acid chloride in DCM (30 mL) ,a solution of 1,1,1,3,3,3-hexamethyldisilazane (30 mmol) in DCM (10 mL) was added dropwise at 0 C, and the solution was then allowed to warm to room temperature. After stirring overnight, the reaction system was quenched with 1 M HCl aq. and saturated aqueous NH4Cl (excess amount) and the organic layer was separated. The aqueous layer was extracted with DCM (2x15 mL). The combined organic layers were washed with saturated aqueous NH4Cl (30 mL) and brine (30 mL), dried over MgSO4, filtered and evaporated in vacuo. The resulting crude material was purified by recrystallization from EtOAc and hexane. The resulting product (5 mmol), 8-bromomethylquinoline (6 mmol), Al2O3 (50 mmol), KOH (25 mmol) and dioxane (30 mL) were added to an over-dried 100 mL three-necked flask. The mixture was stirred for 8 h at 60 C and then was filtered through a celite pad. The filtrate was washed with H2O (30 mL) and the organic layer was separated. The aqueous layer was extracted with EtOAc (2x15 mL). The combined organic layers were washed with brine (15 mL), dried over anhydrous Na2SO4, filtrated and evaporated in vacuo. The resulting crude amide was purified by column chromatography on silica gel (eluent: hexane/EtOAc = 1/1).

78% Use of Iron Oxide-Pd Complexes in Solid Phase Suzuki Cross-Coupling ReactionsThe reaction scheme is presented in FIG. 4. A typical solid-phase Suzuki cross-coupling reaction was as follows. First, a solid phase polystyrene resin (1% divinylbenzene crosslinked, 200-400 mesh) was loaded with aryl halogens (J. Org. Chem. 2006, 71, 537). Then, the aforementioned resin (1.22 g) loaded with an aryl halogen (1 mmol) was added to a mixed suspension of the arylboronic acid (2 mmol) and K2CO3 (2 mmol) in 20 mL of DMF containing Iron Oxide-Pd (4 nm) (30 mg, 0.87 mol %). The mixture was heated to 80 C. and was maintained at this temperature for 6 days. Iron Oxide-Pd was magnetically concentrated using an external permanent magnet. To this end, the mixture was vigorously shaken. A permanent magnet was then applied externally. Magnetic nanoparticles were concentrated on the sidewalls of the tube (horizontal direction) while some resins were suspended in solution or precipitate at the bottom of the tube (vertical). The suspended and precipitated resins, as well as the solution, were transferred out of the tube using a pipette. This process usually needed to be repeated more than eight times to ensure that most of nanoparticles were removed from resins. Iron Oxide-Pd was then washed with methanol (10×200 mL). Afterwards, magnetic nanoparticles were further washed with water (5×100 mL) and methanol (5×100 mL). The nanoparticles were then air-dried and used directly for a new round of Suzuki reaction.The resins and excessive arylborate were separated via filtration. The beads were recovered as the filter and subsequently washed with methanol (5×100 mL) and water (5×100 mL). The cleavage of the Suzuki product out of the resins was achieved by adding the solid-phase beads (1.18 g) and NaOH (2 mmol) to a mixture of ethanol (15 mL) and water (15 mL). The mixture was heated to reflux and stirred at this temperature for 2 days. After cooling down to ambient temperature, resins were filtered off and the filtrate was neutralized with 1 M HCl to pH 7. Solvents were removed in vacuo and the residues were extracted with ethyl acetate (10×50 mL). The combined organic solutions were dried over anhydrous Na2SO4 and subjected to HPLC and NMR analyses. A simple recrystallization step was also employed using EtOH/H2O to improve the purity of the Suzuki product. The structures of isolated Suzuki products were determined by 1H NMR, IR and high-resolution MS. HPLC analyses of isolated products after recrystallization showed that high purity (>99%) was obtained. A UV detector with a fixed wavelength of 254 nm was employed for signal detection. A typical HPLC analysis program used a solvent gradient starting from 40% H2O in CH3CN to 10% H2O in CH3CN in 6 min followed by 10% H2O in CH3CN for additional 9 min with a flow rate of 0.5 mL/min.The yields of the solid-phase cross-coupling products were summarized in Table 3. The Iron Oxide-Pd nanocomplex effectively catalyzed these reactions. TABLE 3 Suzuki Cross-Coupling of Aryl Halogens (on Resins) and Arylboronic Acids (in Solution) under Iron Oxide-Pd (4 nm).
