実験手順

To 8 mL of the sodium polysulfide solution of Example 1 was added 1-bromo-2-methoxy ethane (3.7 g) with stirring at 22-25° C. Extraction of the reaction mixture with ether, washing of the ethereal solution with water, and concentration gave an oil. Distillation of the oil yielded 1.0 g of bis(methoxyethyl)disulfide. Analysis of the oil gave the following results: C, 38.27%; H, 7.82%; S, 36.18%. Calculated for C6H14O2S2: C, 39.56%; H, 7.69%; S, 35.16%.
