2-hydoxy-alkyl t-butyl sulphoxides. They decomposed readily to 1,1-diaryl-2-methylprop-1-enes, but two of them were isolated in crystalline form. The determination of the crystal structure of 4-bis-(p-fluorophenyl)-3,3-dimethyl-1,2-oxathietan 2-oxide showed that the oxathietan ring was non-planar, with sulphinyl oxygen pseudo-axially orientated.
通过2-羟基-烷基叔丁基亚砜的氧化环化反应制备了三个4,4-二芳基-3,3-二甲基-1,2-氧杂蒽酮2-氧化物。它们很容易分解为1,1-二芳基-2-甲基丙-1-烯,但其中两个以结晶形式分离。对4-双-(对氟苯基)-3,3-二甲基-1,2-氧杂蒽酮2-氧化物的晶体结构的测定表明,该氧杂蒽环是非平面的,其中亚硫酰氧是伪轴向取向的。
