MTSHE,13700-08-8,雜環有機化合物存儲條件:-20°C
Some methanethiosulfonates are hygroscopic and all hydrolyze in water, over a period of time, particularly in the presence of nucleophiles. They should be stored in a desiccator at minus 20 degree C and warmed up to room temperature before opening the vial. For maximum results, solutions should be made up immediately prior to use even though solutions in distilled water appear to be stable for hours at 4 degree C.
MTSHE的合成:
1)將CH3SO2Cl(5.9g)在乙醇(9.2ml)中的溶液滴加到Na2S(46.98mmol)在乙醇中的冷凍(-15C)溶液(34.5ml)中。
2)將反應混合物在室溫下攪拌12小時。過濾并從乙醇中結晶后,得到鈉,為白色固體。
3)將鈉(2.5克;18.64毫摩爾)溶于30毫升乙醇中,并滴加2-溴乙醇(2.6毫升;37.28毫摩爾)在乙醇(6毫升)中的溶液。
4)將溶液在氮氣下在100℃下加熱8小時。過濾混合物,將溶液蒸發至干,將殘余物溶解在CHCl3中并用水萃取。
5)將水溶液蒸發至干,向殘余物中加入(THF),過濾所得懸浮液。蒸發THF溶液,得到作為油狀黃色產物的MTSHE。
