YieldReaction ConditionsOperation in experiment
50 % de With tetrapropylammonium nonabromide In dichloromethane at 0℃; for 0.0833333 h; Inert atmosphere General procedure: A 0.66 M Pr4NBr9 in CH2Cl2 solution was prepared as described in General Procedure A. A 10-mL round-bottom flask equipped witha magnetic stir bar was charged with CH2Cl2 (1 mL) and the desired substrate (2 mmol). This solution was cooled to 0 °C and the Pr4NBr9 solution (0.75 mL, 25 molpercent) was added dropwise. The mixture was allowed to warm to r.t. and stirred for the reported time. Then the reaction was quenched and worked up as described in General Procedure A.
80 %Spectr. With sulfuric acid; C20H21BrCuN4O; oxygen; lithium bromide In acetonitrile at 70℃; for 24 h; A reaction flask was loaded with 33 m-(MeO)2C6H4 (0.3mmol), 34 LiBr (0.45mmol), Cu complex (5molpercent) and 67 H2SO4 (0.3mmol) in 19 CH3CN (0.5mL). The mixture was heated at 70°C under oxygen atmosphere for 24h. The product yields were determined by 1H NMR integration with the use of methylsulfone as the internal standard in 68 CDCl3.
