其中的一个例子
Reaction of 3,3-bis(chloromethyl)oxetane with sodium thiosulfate.
A mixture of 99 g. (0.4 mole) of sodium thiosulfate
pentahydrate in 100 ml. of water and 31 g. (0.2 mole) of
bis(chloromethy1)oxetane in 150 ml. of ethanol was refluxed
with stirring overnight. Two. liquid phases of about equal
volume were prevent initially, but merged to one after about
1-2 hr. refluxing, indicating that the reaction was probably
complete. The reaction mixture was diluted with an equal
volume of alcohol, and allowed to stand overnight again.
The fine needle-like crystals were filtered and dried. The
solid was boiled with 85% ethanol, which dissolved most of
the product. The hot solution was filtered, and allowed to
cool. After several hours, the needle-like crystals were
filtered, recrystallized once more from the minimum amount
of 85% ethanol and dried at room temperature. The yield
was 57 g.
