Reaction Conditions:
with tri-tert-butyl phosphine;5%-palladium/activated carbon;sodium t-butanolate in o-xylene at 110; for 2 h;Inert atmosphere;
Steps:
6 Example-6
A cooling tube, round bottom flask 50mL equipped with athermometer, at room temperature, bromobenzene 1.4g in a nitrogen atmosphere(9.0 mmol), 3- methyl-diphenylamine 1.1 g (6.0 mmol), palladium supported materialB 0 .13g (palladium atom 0.12mmol), was mixed with sodium -tert- butoxide 0.86g(9.0mmol) and o- xylene 6.0g. After nitrogen is a flow of about 20 minutes, tri(tert- butyl) phosphine (hereinafter, "P- (tBu) 3" and also indicate)36.4 mg (0.18 mmol) was dissolved o- xylene ( 150 uL) was added and undernormal pressure, pressurized to 110 ° C.It was raised and the mixture was stirred for 2 hours after.Incidentally, the yield by gas chromatography, was calculated by internalstandard method with an internal standard substance n- eicosane. The resultsare shown in Table 1.
