Alkyl thionacetates undergo thermal elimination by a homogeneous unimolecular mechanism to give alkenes and thioacetic acid as first products. With the primary esters there is an accompanying rearrangement to thiolacetate. A transition state similar to that for acetate pyrolysis is proposed for the elimination reaction, but it is argued that it is more product-like in the thionester case.
亚烷基硫代乙酸酯通过均相的单分子机理进行热消除,得到烯烃和硫代乙酸作为第一产物。对于伯酯,伴随着重排成硫羟乙酸酯。对于消除反应,提出了一种类似于乙酸盐热解的过渡态,但据认为在亚硫酸酯情况下它更像产物。
