実験手順

A mixture of 2,2,2-trifluoroethyl bromide (9.8 g), sodium sulphide nonahydrate (14.4 g), sulphur (1.9 g), hexadecyl tributyl phosphonium bromide (1.0 g) and water (18.0 g) was charged to a Carius tube under a nitrogen atmosphere and the tube sealed. The tube was heated to 70° C. for 8 hours, cooled and the contents subjected to steam distillation to give bis-(2,2,2-trifluoroethyl) disulphide as an oil in a yield of 67° C. The product was identified by GC-mass spectroscopy.
