5-Chloro-m-xylene Usage And Synthesis
Uses
3,5-Dimethylchlorobenzene can be used as an intermediate in the synthesis of other compounds and has been shown to be effective in the synthesis of tetrafluoroboric acid, sodium nitrite and palladium chloride.
Synthesis
A solution of 3,5-dimethylaniline (36.3 g; 0.3 mole) in glacial acetic acid (200 ml) is treated with methanesulfonic acid (60 g), and the stirred mixture cooled to 0°-5° C. in an ice-salt bath. An ice-cold solution of sodium nitrite (21 g in 80 ml H2O) is slowly added over a half-hour period. This diazonium solution is then added quickly to an ice-cold solution of cuprous chloride [from cooper sulphate 5 H2O (125 g), sodium chloride (32.5 g) and sodium sulphate (71 g)] in concentrated hydrochloric acid (160 ml). The mixture becomes very thick and is allowed to warm to room temperature. The stirring is continued overnight, and the solution is heated to 60° C. for 1/2 hour. Concentrated ammonia is added with cooling until the solution is alkaline, and the oil is extracted with ether. The dried ether extract distillation gives 5-chloro-m-xylene, b.p. 70°-73°/12 mm (25.6 g).
