both the methoxy group and the thiolate unit of the dithiane ring, giving dioctyl ketone after oxidation, but the yield is low, primarily because thiophilic addition of the lithiating agent predominates over lithiation. Again, there is no evidence for the displacement of the sulfenate unit. However, the intermediate prior to oxidation can be treated with trifluoroacetic anhydride to induce a Pummerer
各种 2-取代的 1,3-二噻烷氧化物(1-氧化物和 1,3-二氧化物)已被金属化并首次与三烷基硼烷(三辛基硼烷)反应。2-氯-1,3-二氧化物导致辛基从硼迁移到碳,同时取代氯并在氧化后生成壬酸,但没有证据表明第二次迁移涉及次磺酸盐基团的置换。2-甲氧基-1-氧化物锂化反应导致两次迁移,甲氧基和二噻烷环的硫醇盐单元均被置换,氧化后得到二辛基酮,但产率低,主要是因为亲硫性锂化剂的添加优于锂化。同样,没有证据表明次磺酸盐单元发生了位移。然而,
