93% | With C24H20Cl2NPPdS; potassium carbonate; palladium; In toluene; at 100℃; for 2h; | General procedure: A 100 ml round bottom flask was fitted with a reflux condenser and a magnetic stirrer bar. The flask was charged with toluene (15 ml) and the appropriate amount of catalyst reagents and the internal standard (n-Decane: 2.59 mmol). The contents were thoroughly mixed and an initial sample (t0) was then taken. The reaction flask was placed in an oil bath at the desired temperature and the reaction mixture allowed to heat/reflux with stirring. A sample was taken and analyzed every 10 min for the first hour and every 30 min thereafter until t3h. In cases where conversionwas not complete after 3 h, the reaction mixturewas then allowed to stir for a total of 24 h. The reaction at 140 C was performed in a sealed tube. All catalytic reactions were done under aerobic conditions. Percentage conversions were determined by GC with n-decane as the internal standard and the coupling products were characterized by mass spectrometry (Table 4) as well as 1H NMR spectroscopy (Entry 5, Table 4 only). |

In nitrobenzene; | Example 58 Intermediate 58A 1-(4'-butyl[1,1'-biphenyl]-4-yl)-1-ethanone 5g (24mmol) <strong>[37909-95-8]4-butylbiphenyl</strong> and 3.96g (30mmol) aluminiumchlorid are dissolved in 30ml nitrobenzene. At a temperature below 20C 1.87g (30mmol) acetylchloride is added dropwise and the reactionmixture is stirred at roomtemperature for 2hrs. The solution is poured onto icewater, the organic phase is separated, the aqueous phase extracted with ethylacetate, the combined organic phases are washed with water and brine, dried and concentrated. The product is obtained by trituration with petrolether. Yield: 3.07g (51%). 200 MHz 1H-NMR (CDCl3): 0.96, t, 3H; 1.40, m, 2H; 1.65, m, 2H; 2.62, s, 3H; 2.68, t, 2H; 7.30, d, 2H; 7.58, d, 2H; 7.69, d, 2H; 8.02, d, 2H. |
