反応手順

Zirconium phenoxide (4.0 g, 0.0086 moles) was added to phenol (8.9 g, 0.095 moles) and ethyl disulfide (10.5 g, 0.086 moles). The mixture was heated under nitrogen for 6.5 hours during which the temperature slowly increased to 195° C. Ethyl mercaptan was removed continuously by distillation. The mixture was distilled at 0.4 mm mercury to a maximum head temperature of 102° C. yielding 12.2 g of distillate. Gas chromatographic (GC) analysis indicated the distillate contained 5.0 g of ortho-(ethylthio)phenol (38% yield).
