1,3-dichloropropene in the system hydrazine hydrate–KOH to form bis(1-chloroprop-1-en-3-yl) sulfide, and in the system hydrazine hydrate–monoethanolamine, bis(1-chloroprop-1-en- 3-yl) disulfide. The reaction of tellurium in the system hydrazine hydrate–KOH leads to diallyl telluride, the product of nucleophilic substitution of the allylic chlorine atom and reductive cleavage of the С sp2–Cl bond. The
硫与水合肼-KOH体系中的1,3-二氯丙烯反应生成双(1-氯丙-1-烯-3-基)硫化物,水合肼-单乙醇胺中硫与双(1-氯丙-1- (3-基)二硫化物。碲的系统中的水合肼-KOH导致二烯丙基碲的反应中,烯丙基氯原子的亲核取代和С的还原裂解的产品SP 2 -Cl键。硒与1,3-二氯丙烯的反应生成了复杂的产物混合物。在过量的KOH(Se:KOH = 1:5)下,分离出双(1-氯丙-1-烯-3-基)硒化物。
