Cesium fluoride → (Fluoromethyl)(p-tolyl)sulfane

Cesium fluoride (149.55 g, 2 eq) was added to a mixture of PEG400 (90 mL) and acetonitrile (540 mL). The mixture was stirred a few minute under an argon atmosphere and then acetonitrile (90 mL) was removed by distillation. (Chloromethyl)(p-tolyl)sulfane (102.68 g, 492.25 mmol) was added. The reaction mixture was stirred at a temperature between 80° C. and 85° C. until the reaction was complete. The suspension formed, was filtered and the filtrate was concentrated. The crude product was purified by distillation to give 52.09 g (68%) of the desired product as slightly yellow oil (bp: 57° C. at 40 Pa).
