Pathways in nucleophilic fission of hydroxythietanes are determined by the oxidation state of sulphur; for eliminative fission, activation parameters, substituent effects, and comparison with unstrained analogues all suggest a greater degree of ring cleavage in the transition structure for thietanes than for cyclobutanes.
羟基硫杂环丁烷亲核裂变的途径由硫的氧化态决定。对于消除裂变,活化参数,取代基作用以及与未拉伸的类似物的比较均表明,硫杂环丁烷比环丁烷在过渡结构中的环裂解程度更高。
