  Mechanochemistry Frees Thiourea Dioxide (TDO) from the ‘Veils’ of Solvent, Exposing All Its Reactivity

  摘要：

  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。

With the assistance of computational chemistry, a set of derivatives presenting a large range of redox potentials (from −1.1 to −0.45 V) was designed and provided a list of suitable molecules to be synthesized and tested.

  The reduction of several aromatic nitro compounds to amines by means of the two novel catalytic systems ([IMes]2ReOBr3)/PhSiH3 and ([Py]3ReNOBr2)/PhSiH3 under microwave irradiation is here reported. These two systems were able to perform the reduction of nitro groups with higher TON and TOF when compared with previously reported systems based on oxo-rhenium core under standard heating, although they
