Reaktionsschritte

A mixture of 1-chloro-2,2,2-trifluoroethane (20 g), benzyl mercaptan (12.4 g, 99% strength), sodium hydroxide (22.0 g of a 22% aqueous solution) and hexadecyl tributyl phosphonium bromide (0.51 g) was charged to a resealable Carius tube under a nitrogen atmosphere and heated at 70° C. for 10 hours. The tube was then cooled to 0° C., unsealed and the contents separated into two layers. The lower organic layer was collected, washed with water and purified by short path distillation to give 2,2,2-trifluoroethylthiomethylbenzene, b.p. 60°-70° C./ 10 mmHg, 17.4 g (yield 84%, strength 99%). The identity of the product was confirmed by gc-mass spectroscopy and nuclear magnetic reconance, and by comparison with data provided in C. Bunyagidj et al, J Org. Chem., 1981, 46 3335.
