Electrochemistry has been widely used in energy storage, metallurgy, chemical synthesis and other fields since its birth using electricity as one of the cheapest reagents. However, compared with the revival of electrochemical synthesis of small molecules, the electrochemical polymerization for preparing macromolecules is still rudimentary due to formidable challenges. Herein, A unique electrochemical polymerization is disclosed between CS2 and diamines at room temperature in an electrolyte‐free manner to access poly thioureas. Polythioureas have high selectivity for four metal ions, including Au3+, Ag+, Pt4+, and Hg2+, and can be used as an efficient adsorbent for recovering gold from metal waste. [ABSTRACT FROM AUTHOR]

An electrochemical three-component reaction involving elemental sulfur is disclosed for achieving a metal-free, oxidant-free synthesis of thioesters in a high atom-economical, step-economical and chemoselective manner. A mechanistic investigation indicates that the use of elemental sulfur to trap acyl radical derived from radical umpolung of α-keto acid with an electrochemical design can efficiently generate a carbonyl thiyl radical, which can further be captured by diazoalkane to afford various thioesters.

A series of 1,4-disubstituted 1,2,3-triazoles containing formyl was synthesized from a variety of readily available nitrobenzaldehydes and alkynes via a convenient one-pot, click-SNAr reaction with moderate to excellent yields. The reactions were easily carried out in hexamethyl phosphoramide in the absence of a base at 60 °C. [ABSTRACT FROM PUBLISHER]

An abstract of the article “Cu(I)-Promoted One-Pot Click-SNAr Reaction of Nitrobenzaldehydes" by M. Bohle is presented.
