Iron/dppbz-catalyzed Decarboxylative Couplings of Active Esters
In a screwed-capped vial active ester (0.1 mmol), Fe(acac)3 (0.005 – 0.04 mmol) and dppbz (0.006 – 0.048 mmol) are weighed. The vial is then sealed, evacuated and back-filled with Ar. Then, 0.5 mL of distilled THF is added. The mixture is stirred for 5 minutes under Ar and diarylzinc reagent in THF (ca. 0.3 mol/L, 0.15 – 0.25 mmol) is added in one portion at 0 - 25 °C to the mixture and stirred at the same temperature for 1 h. After this time, the reaction is quenched with 1 mol/L HClaq, sat. NH4Claq or H2O and diluted with diethyl ether. The organic layer is separated and dried over Na2SO4 anhydrous, filtered and evaporated to dryness. Pure products are obtained after column chromatography or preparative TLC.

Iron-Catalyzed ortho-Alkylation of Carboxamides
Typical procedure (R = benzyl): To Fe(acac)3 (17.1 mg, 0.05 mmol), dppe (29.9 mg, 0.075 mmol), and 3-methyl-N-(quinolin-8-yl)benzamide (131 mg, 0.5 mmol) are added THF (4 mL), and benzyl chloride (190 mg, 1.5 mmol). The mixture is then placed in an oil bath at 65 °C and PhMgBr (16% in THF, ca. 1 mol/L) (0.6 mL, 0.6 mmol) is added in a single portion. Upon completion of PhMgBr addition, the reaction mixture is stirred at 65 °C for 1 min. Then PhMgBr (16% in THF, ca. 1 mol/L) (1.3 mL, 1.3 mmol) is added dropwise at 65 °C for 9 min. The reaction mixture is stirred at 65 °C for 1 min and brought to rt. Subsequently the reaction mixture is quenched with a saturated solution of ammonium chloride (535 mg, 0.01 mol) and extracted with dichloromethane (3 x 3 mL). The combined organic extracts are dried over MgSO4, filtered and concentrated to give a residue. The residue is purified by silica gel flash chromatography (eluent: hexanes/EtOAc = 20:1) to give 2-benzyl-5-methyl-N-(quinolin-8-yl)benzamide (175 mg, 99% yield) as a white solid.

Efficient Fe/Cu Co-Catalyzed C-N Cross-Coupling Reaction
Typical procedure (Entry 1): A Schlenk tube is charged with p-anisidine (92.4 mg), K2CO3 (138 mg), Fe(acac)3 (34.4 mg), and Cu(OAc)2· H2O (20 mg). Under a nitrogen atmosphere, 4-bromotoluene (85.5 mg) is added followed by dry DMF (0.8 mL). The reaction mixture is then heated to 135 °C, and stirred for 20 h. The mixture is cooled to room temperature and diluted with diethyl ether. The resulting suspension is filtered through a celite pad and the filtrate is concentrated. The residue is purified by column chromatography on silica gel (eluent: petroleum ether/ethyl acetate) to give 4-methoxy-N-p-tolylaniline (98.1 mg, 92 %).
