1.Oxidize toluene to benzoic acid using potassium permanganate.
2.Treat benzoic acid so formed with sodium metal to replace acidic hydrogen and form sodium benzoate.
3.Heat the benzoic acid with soda-lime. You will get first sodium benzoate, PhCOONa, and then benzene:
PhCOONa + NaOH -----> PhH + Na2CO3..
