YieldReaction ConditionsOperation in experiment
30% General procedure: General Procedure for Bi-Functional Kumada Coupling (Protocol A): A reaction flask was charged with magnesium turnings (2.4 eq.) and anhydrous diethyl ether and flushed with argon. A small amount of the bromothiophene was added to initiate the reaction, followed by the dropwise addition of balance of the bromothiophene (2 eq. total) as a solution in anhydrous diethyl ether at such a rate as to maintain a mild reflux. After the addition was complete, the reaction was refluxed for a further 30 minutes. The mixture was cooled to RT, and the liquid portion was transferred to an addition funnel and added dropwise to a solution of <strong>[3141-24-0]2,3,5-tribromothiophene</strong> (1 eq.) and [1,1?-bis(diphenylphosphino)ferrocene]dichloropalladium (II) (Pd(dppf)Cl2) (0.4 mol %) in anhydrous diethyl ether. The reaction mixture was stirred for 16 h at room temperature, then was poured over ice and quenched with 5% HCl. The organic portion was separated and the aqueous layer was extracted with diethyl ether. The combined organic extracts were washed with brine, dried over MgSO4, filtered and solvent removed by rotary evaporation. Flash chromatography afforded the product, which was sonicated in methanol, filtered and dried to give an off-white powder. (9) was prepared on 3.9 mmol scale (30% yield) according to protocol A. 1H NMR (600 MHz, CDCl3) delta 7.09 (s, 1H), 6.93 (s, 1H), 6.85 (s, 1H), 2.36 (s, 3H), 2.34 (s, 3H), 2.15 (s, 3H), 2.12 (s, 3H).
