  • Electrochemically selective double C(sp<sup>2</sup>)–X (X = S/Se, N) bond formation of isocyanides

    The construction of C(sp2)–X (X = B, N, O, Si, P, S, Se, etc.) bonds has drawn growing attention since heteroatomic compounds play a prominent role from biological to pharmaceutical sciences. The current study demonstrates the C(sp2)–S/Se and C(sp2)–N bond formation of one carbon of isocyanides with thiophenols or disulfides or diselenides and azazoles simultaneously. The reported findings could provide
    C(sp 2 )–X (X = B、N、O、Si、P、S、Se等) 键的构建引起了越来越多的关注,因为杂原子化合物在从生物学到制药科学中发挥着重要作用。目前的研究表明 C(sp 2 )–S/Se 和 C(sp 2)–异氰化物的一个碳与苯硫酚或二硫化物或二硒化物和氮唑同时形成N键。报告的发现可以提供新的多种异硫脲,尤其是迄今为止很少报道的硒脲。该协议显示出良好的原子经济性和阶梯经济性,仅析氢和理论计算解释了产品的立体选择性。重要的是,无论是否存在敏感的自由基受体,如广泛的芳烃和炔基部分,甚至烯基部分,电化学反应都可能只发生在异氰基部分。

    A general strategy to prepare substituted 3-bromo- and 3-chloropyrazoles is described. The three-step method involves condensation of crotonates or β-chloro carboxylic acids with hydrazines, followed by halogenation and oxidation. Several condensation and oxidation protocols were developed to enable preparation of a wide variety of 3-halopyrazoles with good to excellent yields and regiocontrol.
