  IT is known that there is no reaction between hydrogen sulphide and sulphur dioxide in the dry state, and that mercury, benzene, or carbon tetra-chloride have no effect on a mixture of the dry gases.

  众所周知，干燥状态下的硫化氢和二氧化硫之间没有反应，并且汞、苯或四氯化碳对干燥气体的混合物没有影响。
• Study of the oxidation of SO2 dissolved in 0·5 M H2SO4 on a gold electrode—I stationary electrode

  日期：1975.6

  The oxidation of sulphur dioxide dissolved in 0·5 M H2SO4 on a stationary gold electrode was studied by the method of cyclic voltametry. The rate of this reaction strongly depends upon the electrochemical pretreatment of the electrode directly in the SO2 solution. This effect is connected with the fact that SO2 is reduced on the gold at potentials more negative than +0·4 V (vs he), with formation of

  采用循环伏安法研究了固定在金电极上溶解在0·5 MH 2 SO 4中的二氧化硫的氧化。该反应的速率强烈取决于直接在SO 2溶液中对电极的电化学预处理。这种效果与以下事实有关：在金上，SO 2在比+ 0·4 V（vs he）更大的负电势下被还原，形成两种不同形式的吸附“还原SO 2 ”，显然是吸附了硫和H 2。 S.

  The synthesis of nitrogen-based heterocycles has always been considered essential in developing pharmaceuticals in medicine and agriculture. This explains why various synthetic approaches have been proposed in recent decades. However performing as methods, they often imply harsh conditions or the employment of toxic solvents and dangerous reagents. Mechanochemistry is undoubtedly one of the most promising technologies currently used for reducing any possible environmental impact, addressing the worldwide interest in counteracting environmental pollution. Following this line, we propose a new mechanochemical protocol for synthesizing various heterocyclic classes by exploiting thiourea dioxide (TDO)’s reducing proprieties and electrophilic nature. Simultaneously exploiting the low cost of a component of the textile industry such as TDO and all the advantages brought by a green technique such as mechanochemistry, we plot a route towards a more sustainable and eco-friendly methodology for preparing heterocyclic moieties.

  氮基杂环的合成一直被认为是开发医药和农业药物的关键。这也是近几十年来提出各种合成方法的原因。然而，这些方法通常条件苛刻，或需要使用有毒溶剂和危险试剂。机械化学无疑是目前最有前途的技术之一，可用于减少可能对环境造成的影响，从而解决全球对环境污染问题的关注。根据这一思路，我们提出了一种利用二氧化硫脲（TDO）的还原性和亲电性合成各种杂环类化合物的新机械化学方案。同时利用二氧化硫脲（TDO）这种纺织工业成分的低成本以及机械化学这种绿色技术所带来的所有优势，我们为制备杂环类化合物规划了一条更具可持续性和生态友好型的方法路线。
