oxygen-containing nucleophiles, the dialdehyde formed crystalline linear derivatives and the only cyclic compounds readily obtained were 2-acetoxy-6-phenylthio-1,4-oxathian 4,4-dioxide and 1,4-dithian-2,6-diol 4,4-dioxide. 2,2′-Sulphonyldi(acetaldehyde oxime) was dehydrated to sulphonyldiacetonitrile, also prepared by oxidation of the known thiodiacetonitrile. An alternative approach to the dialdehyde
描述了通过酸催化2,5-二氢噻吩1,1-二氧化物与3,4-环氧四氢噻吩1,1-二氧化物和反式-四氢噻吩-3,4-二醇1,1-二氧化物的可再现方法。过氧化氢。先前关于乙酸和甲酸的影响的混乱说法已得到澄清。该反式-以及更多的反应顺-二醇被高碘酸盐氧化为2,2'-磺酰基二乙醛。与含氮,硫或氧的亲核试剂反应,二醛形成结晶线性衍生物,唯一容易获得的环状化合物是2-乙酰氧基-6-苯硫基-1,4-氧杂亚砜4,4-二氧化物和1, 4-二噻吩-2,6-二醇4,4-二氧化物。将2,2'-磺酰基二(乙醛肟)脱水成磺酰基二乙腈,也可通过氧化已知的硫代二乙腈来制备。通过将硫酰氯添加到乙基乙烯基醚中来替代二醛的方法是不成功的。
