Name is 1,1′-Dibromoferrocene, as a common heterocyclic compound, it belongs to iron-catalyst compound, and cas is 1293-65-8, its synthesis route is as follows.,1293-65-8
In a Schlenk tube CuI (100 mg, 0.53 mmol), PPh3 (1.60 mmol),1,1?-dibromoferrocene (1.8 g, 5.2 mmol), 4-t-butylphenol(1.02 g, 1.3 eq.), and Cs2CO3 (1.86 g, 1.1 eq.) were dissolved in toluene (35 mL), and the reaction mixture was stirred at 110 C for 26 h. After evaporation of the volatiles, the crude product was purified by silica column chromatography (cyclohexane-ethyl acetate). Of a light-yellow fraction, the solvent was removed, which resulted in 930 mg (43 %) of a yellow-brownish solid. – Rf = 0.65 [cyclohexane-ethylacetate (20:1)]. – 1H NMR (CDCl3): delta = 1.22 (s, 9 H; CH3), 3.95 (t, J = 1.9 Hz, 4 H, Cp), 4.21 (t, J = 1.9 Hz, 4 H, Cp), 6.87 (d,J = 8.6 Hz, 2 H, phenyl H2, H6), 7.19 ppm (d, J = 8.6 Hz, 2 H,phenyl H3, H5). – 13C NMR (75 MHz, CDCl3): delta = 31.7 (CH3), 34.4 (CCH3), 60.8 (C5H4), 64.2 (C5H4), 68.2, 68.8, 77.6, 117.0,123.2, 126.2, 145.4, 156.4 ppm.
With the complex challenges of chemical substances, we look forward to future research findings about 1,1′-Dibromoferrocene
