Reaction Steps

Under the atmosphere of argon, 3.4 g (14 mmole) of 2-chloro-anthraquinone, 5 g (17 mmole, 1.2 eq) of 2-biphenylylboronic acid, 0.32 g (0.35 mmole; 5% by mass Pd) of tris(dibenzylideneacetone)dipalladium(0) and 14 g (43 mmole; 2.5 eq) of cesium carbonate were suspended in 40 ml of anhydrous dioxane. Then, 1.1 ml (25% by mass; 0.98 mmole; 1.4 eq to Pd) of a toluene solution of tricyclohexylphosphine was added, and the resultant mixture was stirred at 80° C. for 10 hours.
