摘要:
Dehydrochlorination of 2-chloroprop-2-en-1-yl sulfides on heating with solid potassium hydroxide afforded the corresponding 1-(organylsulfanyl)propynes in moderate to high yields and minor isomeric allene derivatives, organylsulfanylpropadienes.

for the synthesis of 2-chloroprop-2-en-1-yl sulfones in 47–94% yield. The molecular and crystal structures of 2-chloroprop-2-en-1-yl phenyl sulfone and 2-chloroprop-2-en-1-yl methyl sulfone were determined by X-ray analysis. π-Stacking interaction between the benzene ring and double bond was revealed in the crystal structure of 2-chloroprop-2-en-1-yl phenyl sulfone. Chloropropenyl sulfones were found

carbenylation of sulfur atom followed by 2,3-sigmatropic rearrangement with subsequent dehydrochloration and cyclopropanation of the terminal double bond. The resulted trichlorocyclopropane derivatives were studied by 1H and 13C NMR spectroscopy as well as X-ray single-crystal analysis that revealed intramolecular CH-π interaction and the formation of intermolecular halogen bonds.
摘要 通过(2-氯丙-1-烯-3-基)硫化物反应合成了一系列新型1,1,2-三氯-2-[2-氯-2-(有机硫烷基)乙烯基]环丙烷2a-f。与由 CHCl3 生成的二氯卡宾。该过程显然是通过硫原子的羰基化,然后是 2,3-σ 重排以及随后的脱氯化氢和末端双键的环丙烷化来进行的。所得三氯环丙烷衍生物通过 1 H 和 13 C NMR 光谱以及 X 射线单晶分析进行研究,表明分子内 CH-π 相互作用和分子间卤素键的形成。

Procedure of synthesis of sulfides containing a chloropropenyl fragment sensitive to bases was modified. The change in the sequence of reagents addition ensuring a contact of isothiouronium salt with a minimal base quantity and the application of a mixture hydrazine hydrate-alkali allowed the preparation of target sulfides under mild conditions in up to 93% yields.
