Reaction Conditions:

with tetrakis(triphenylphosphine) palladium⁽⁰⁾;sodium carbonate in ethanol;toluene; for 12 h;Reflux;

Steps:

Reaction Formula 10a

Bromonitrobenzene 20 g (99 mmol), dibenzothran1-yl-boronic acid (25.1 g, 118.8 mmol), Pd(pph3)4 (4.583.96 mmol) and Na2CO3 (31.5 g, 297 mmol) were dissolved in a mixture of ethyl alcohol (148 mE) and toluene (267 mE). The mixture was refluxed/stirred for 12 hours. After completion of the reaction, the resultant was extracted by distilled water and colunmed in a silica-gel such that 4-(2- nitrophenyl)dibenzo[b,d]furan (29.3 g, yield: 100%) was obtained.
