Sulfoxides bearing thioester and ester groups at the α position under heating at ca. 140°C undergo Pummerer thermal rearrangement. However, for sulfonyl sulfoxide, a complex mixture of products is formed. Plausible mechanism is advanced. GRAPHICAL ABSTRACT
在 α 位带有
硫酯和酯基团的亚砜在约 10 ℃加热。140°C进行Pummerer热重排。然而,对于磺酰亚砜,会形成复杂的产物混合物。合理的机制是先进的。图形概要
