Abstract

With the aim of preparing of sulfur-containing derivatives of cymantrene, the hydrolysis of isothiouronium salts of alkylcymantrenes was studied under various conditions as well as subsequent chemical transformations of hydrolysis products. It was found that alkylcymantrenylthiols can be prepared either by hydrolysis of isothiouronium salts under the action of NaOH in a EtOH-acetone (4 : 1) mixture for 2 h or by the reduction of the corresponding disulfides by LiAlH₄ formed in the course of this reaction in good yield for 6 h. Electrochemical properties of disulfides Cym(CHCH₃)SS(CHCH₃)Cym (Cym = C₅H₄Mn(CO)₃) in solution before and after irradiation with a Hg lamp at λ365 nm were studied. The structures of the compounds were established by the X-ray analysis (CymCH(CH₃)SSCH(CH₃)Cym (I) (CIF file CCDC no. 1921952) and CymCH₂SCH₂Cym (II) (CIF file CCDC no. 1921953)).

摘要

为了制备环丙三烯的含硫衍生物，在各种条件下以及随后的水解产物的化学转化中研究了烷基环丙三烯的异硫脲盐的水解。已经发现，可以通过在EtOH-丙酮（4：1）混合物中在NaOH的作用下异硫脲鎓盐的水解2小时或通过在此过程中形成的LiAlH ₄还原相应的二硫化物来制备烷基环十二烷基苯硫醇。反应6小时，收率良好。二硫化物Cym（CHCH ₃）SS（CHCH ₃）Cym（Cym = C ₅ H ₄ Mn（CO）_3的电化学性质研究了在λ365nm的Hg灯照射前后溶液中的）。通过X射线分析（CymCH（CH ₃）SSCH（CH ₃）Cym（I）（CIF文件CCDC No.1921952）和CymCH ₂ SCH ₂ Cym （II）（CIF文件CCDC No. （1921953）。
