Application of 126930-72-1, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 126930-72-1 as follows.
A Schlenk tube was charged with Pd2dba3 (3.0 mg,0.32¡Á10-2 mmol, 8 mol%) and Xphos (3.1 mg, 0.65¡Á10-2 mmol, 16 mol%) in degassed toluene (2 mL). The reaction medium was heated under argon at 60 C for 10 min. To the violet solution was added, under a positive stream of argon, CLM1 (35 mg, 0.04 mmol, 1 eq.), 1-bromo-4-dodecylbenzene 2a (26 mg, 0.08 mmol, 2 eq.), and sodium-tert-butoxide(12 mg, 0.12 mmol, 3 eq.) in 2 mL of degassed toluene. The reaction mixture was heated at 95 C for 24 h. The solvent was evaporated under reduced pressure and the resulting mixture was extracted with DCM from a saturated aqueous solution of NaHCO3 (100 mL). The organic phase was washed with H2O (3¡Á100 mL), The desired product was purified by silica gel column chromatography with DCM/hexane (40:60 v/v) as eluent. Red solid (50 mg, 93%) 1H NMR (600 MHz, CD2Cl2, ppm): delta 7.56 (d, 4H, J=7.8 Hz, ArH), 7.12 (d, 8H, J=7.8 Hz,ArH), 7.03 (d, 12H, J=7.8 Hz, ArH), 2.95 (br, 12H, cyclohexyl-CH2,s),2.60 (t, 4H, J=7.8 Hz, CH2-(CH2)10CH3), 2.35 (s, 6H, CH3,s), 1.85 (br,12H, cyclohexyl-CH2,s), 1.65 (m, 4H, CH2-CH2(CH2)9CH3), 1.33 (m,36H, CH2-CH2(CH2)9CH3), 0.95-0.92 (m, 6H, CH2-CH2(CH2)9CH3); 13CNMR (150 MHz, CD2Cl2, ppm): delta 152.29, 148.39, 146.39, 146.29,137.39, 133.07, 132.63, 130.26, 129.57, 124.84, 124.55, 123.04,35.88, 32.53, 32.23, 30.28, 30.22, 30.13, 29.98, 29.96, 29.76, 26.78,23.29, 22.21, 21.06, 14.48. HR-MALDI-TOF; Calcd. for (M+)C80H104B2FeN8O6 1350.762; found 1350.525 UV-vis: (THF, 10-6 M),lambdamax [nm]=303, 448.
