Reaktionsschritte

A 4-necked, 1-liter flask equipped with a stirrer, a thermometer and a condenser tube was charged with 147.0 g (1.00 mole) of 1,4-dichlorobenzene and 67.9 g (0.10 mole) of an aqueous solution of 50 wt % tetra-n-butylphosphonium bromide. 233.6 g (1.00 mole) of an aqueous solution of 30 wt % sodium thiomethoxide was added dropwise at 80° C. over a period of 6 hours. After addition, the mixture was reacted at the same temperature for 10 hours. After completion of reaction, 157.4 g of a crude 1-methylthio-4-chlorobenzene was obtained by separation procedure.
