Participants

Reaction Steps

42 PARTS OF PHOSPHORUS PENTACHLORIDE IS COVERED WITH A LAYER OF ABSOLUTE ETHER. While stirring and cooling with ice, an ethereal solution of 33.6 parts of hydroxymethylbenzoyl sulfide is dripped in and the whole stirred for 2 hours at room temperature. The solution is filtered, the filtrate concentrated at 0.01 mm and a bath temperature of 40° C, the residue taken up in methylene chloride and washed with cold aqueous NaNHCO3 solution. The organic phase is dried over Na2SO4 and distilled 20 parts of chloromethylbenzoyl sulfide having a boiling point at 0.1 mm of 111° to 113° C is obtained.
