The reaction of 2,2,4,4-tetramethyl-3-thioxocyclobutanone S-oxide with Lawesson reagent (L. R.) afforded the corresponding 1,2,4-trithiolane. Thiopivalophenone and thiopivalophenone S-oxides reacted with L. R. at rt to give the corresponding S-sulfide, which further reacted with thiones to afford the corresponding cis-1,2,4-trithiolanes.
2,2,4,4-四甲基-3-硫酮环丁酮 S-氧化物与 Lawesson 试剂(L. R. )反应,得到相应的 1,2,4-三硫环戊烷。硫代新戊酮和硫代新戊酮 S-氧化物与 L. R. 在常温下反应,得到相应的 S-硫化物,再与硫酮反应,得到相应的顺式-1,2,4-三硫环戊烷。
