Synthesis of Mesoionic 1,3,4-Thiadiazole-2-Thiolates
MolbankA reliable synthesis of C5-unsubstituted 1,3,4-thiadiazole-2-thiolates is described that avoids potentially explosive or laborious steps. This work presents a reliable method for preparing the starting material dithioformate from carbon disulfide and ...

A broadened scope for the use of hydrazones as neutral nucleophiles in the presence of H-bonding organocatalysts [PDF]
, 2006 Using thioureas as H-bonding organocatalysts, nitroalkenes can be activated for the conjugate addition of hydrazones as neutral nucleophiles. Formaldehyde derivatives react at the azomethine carbon as expected, whereas hydrazones from enolizable ...

Isosteric Substitution Enables Rational Design of Two‐Dimensional Energetic Crystals
Advanced Science, EarlyView.Isosteric substitution transforms a classical nitro–amine motif into two‐dimensional aminofurazans with performance beyond TATB. ABSTRACT Two‐dimensional (2D) energetic crystals dissipate mechanical insult via interlayer slip, yet their molecular design space remains narrow.

Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor
Angewandte Chemie, EarlyView.Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...
