反応手順
Following the procedure of Example 24, 50 g (0.3 mole) of 2-mercaptobenzothiazole, 8 mg (0.04 mMole) of Cu(OAc)2.H2O, 40.8 g (2.4 moles) of ammonia and 300 g of water were heated to 50° C., intensively stirred and placed under an oxygen pressure of 4 bars. Uptake of oxygen was immediately recorded and a deposit of dibenzothiazolyl disulphide was formed. After a reaction time of 2.5 hours, the 2-mercaptobenzothiazole conversion amounted to 95.4% and the yield of dibenzothiazolyl disulphide to 94.1% of the theoretical yield (selectivity: 98.6%).
