Reaction Steps
A degassed solution of 40 mmol of 2-chloro-5-trifluoromethylnitrobenzene (starting material) and 40 ml of xylene are placed in an autoclave (volume: 200 ml). 5.0 mmol of TPPTS (in the form of 9.2 g of an aqueous solution containing 0.546 mol of TPPTS/kg of solution) as phosphine and 2.4 g (60 mmol) of NaOH, 23.8 ml of H2O and 1.0 mmol of PdCl2 are added. The pH is from 10.5 to 11.0.
