76% | With 8,8′-biquinoline; palladium diacetate; In water; dimethyl sulfoxide; at 80℃; for 6h;Inert atmosphere; | General procedure: Phenylsulfonylhydrazide (1.1 mmol), nitrile compound (1.0 mmol), palladium acetate (2 mol%) and nitrogen-containing ligand bq (3 mol%) were dispersed in DMSO (2 mL) under inert gas protection, then H2O (2 mmol) was added, and the mixture was heated to 80 C for 6 hours. Then, the reaction solution was extracted three times with Et2O (5 mL), the organic phase was combined, and the solvent was evaporated to drynessThe column chromatography was carried out on a silica gel column (300-400 mesh). The eluting solvent was a mixture of petroleum ether and ethyl acetate to obtain the target product. The reaction conditions and reaction results are shown in Table 4. The reaction formula is as follows: |
74% | With [nickel(II)dichloride(dimethoxyethane)]; Ir[dF(CF3)ppy]2(dtbbpy)PF6; lithium carbonate; 4,4'-di-tert-butyl-2,2'-bipyridine; In water; N,N-dimethyl-formamide; for 72h;Inert atmosphere; Microwave irradiation; | General procedure: EXAMPLE 36 - (4-Fluorophenyl)(phenyl)methanonePrepared according to General Procedure B with l-fluoro-4-iodobenzene (275.0 mg, 2.5 mmol, 5.0 equiv) and L12CO3 (184.8 mg, 2.5 mmol, 5.0 equiv), purified with 5% EtOAc in hexanes as eluent, to yield the product as a pale yellow solid, 70.2 mg, 70% yield.General procedure B for the decarboxylation arylation of keto acids iaryl halide scope"): An oven-dried 40 mL vial equipped with a Teflon septum cap and magnetic stir bar was charged with rr[dF(CF3)ppy]2(dtbbpy)PF6 (11.2 mg, 0.01 mmol, 0.02 equiv), NiC^ glyme (11.2 mg, 0.05 mmol, 0.10 equiv), 4,4'-di-tert-butyl-2,2'-bipyridine (20.1 mg, 0.075 mmol, 0.15 equiv), phenylglyoxylic acid (150 mg, 1.00 mmol, 2.0 equiv), the corresponding aryl halide (0.50 mmol, 1.0 equiv), and L12CO3 (73.9 mg, 1.00 mmol, 2.0 equiv) from a bottle stored in a dessicator. To this vial was added DMF (25 mL) and water (18 iL, 2.00 mmol, 2.0 equiv). The reaction mixture was degassed for 30 minutes by bubbling argon stream, then sealed with parafilm. The vial was irradiated with 34W Blue LED lamp (Kessil KSH150B LED Grow Light) for 72 hours with cooling from a fan (vial temperature reached 37 C). After 72 hours, the reaction was diluted with 25 mL 0 and extracted with 3x75 mL Et20. The combined organic layers were washed with 3x25 mL 0, then dried over MgS(, filtered, and concentrated in vacuo. |
69% | With dipotassium peroxodisulfate; silver nitrate; In water; at 25℃; for 1h; | General procedure: Potassium arylformate (1.0 mmol), potassium phenyl fluoroborate (1.05 mmol),AgNO3 (0.05 mmol) and K2S2O8 (1.5 mmol) were dispersed in water (2 mL) and reacted at 25C for 1 hour.After the reaction was completed, the water was removed, and then the product was isolated by column chromatography. The potassium arylformate was used and the results are shown in Table 4. |

---|---|---|
57% | With dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; potassium carbonate; In dichloromethane; water; at 60℃; | General procedure: All liquids incorporated into the reaction were degassed prior to addition. To a solution of 1 (1 eq., 50.0 mg, 0.192 mmols) and PdCl2(dppf)•CH2Cl2 (20 mol%, 31.3 mg, 0.0384 mmols) in CH2Cl2 (0.1M, 1.6 mL) was added aryl bromide (1.1 eq., 0.211 mmols) and 3.33M K2CO3 solution (6 eq.,0.958 mmols, 0.27 mL). The mixture is quickly stirred and heated at 60. The mixture would go from a bright red solution to a darkened mixture within minutes of the reaction. Upon confirmation of completion by TLC (typically eluted with 40% to 50% MeCN/CH2Cl2), the mixture is immediately taken off the heat and diluted with 10 mL H2O. The organic mixture is extracted with 3 x 10 mL diethyl ether. The organic extracts are dried over Na2SO4, filtered then concentrated. The crude product is purified by silica gel column chromatography (gradient with ethylacetate/hexanes) to afford 3 as a resin or white powder. |
